Poorly timed traffic lights don't just waste precious minutes. Like Google's chief sustainability officer Kate Brandt pointed out at a media event yesterday, they're also bad for the environment and public health. The company unveiled a slew of sustainability-centric products and updates today that aim to help users make more informed, environmentally friendly decisions. But it's also been working on a project that could use AI to make traffic lights more efficient and, as a result, decrease pollution in general. 

When your vehicle stops at an intersection, that idling time leads to wasted fuel and "more street-level air pollution," Brandt said. Google's new project would use AI to measure and calculate traffic conditions and timing at a city's intersections, then time them more efficiently. Brandt said one of the company's AI research groups has been able to accurately calculate and gather this data and train a model to optimize inefficient intersections. 

Google has run pilots at four locations in Israel to date, in partnership with the municipalities of Haifa, Beer-Sheva and the Israel National Roads Company. The company says it's observed a "10 to 20 percent reduction in fuel and intersection delay time" so far. Google didn't share any details on the average daily traffic in those intersections, though a video clip from the event showed a fairly busy junction. The company also didn't explain how the AI would work with current systems and the lights around specific intersections.

"It's early days," Brandt said, "but on the back of these promising results, we are now beginning new pilots in Rio de Janeiro and speaking with other cities around the globe." Though we're likely still at least years away from having AI manage our traffic intersections, this is one of the steps towards the vision of completely smart cities that the industry has collectively been working on for years. 

The idea of letting AI decide when to let vehicles stop or go can seem unsettling at best and potentially risky, but the goal of improving traffic light efficiency is a worthwhile one. Hopefully, with rigorous testing and safety measures in place, we may actually be able to reduce a significant amount of wasted fuel and exhaust-based pollution.

In the third quarter of 2021 Tesla sold 241,300 cars. That's 102,000 more than the same time period last year. Sure, that's only slightly more than half of the 446,997 cars that GM sold in the last three months. But, that number represents a steep 33-percent decline year-over-year for GM. And (if my math is correct) would mean that it sold more cars than Subaru globally over the last three months.

That Tesla has surged while other automakers are struggling isn't a huge surprise once you start digging into the details, though. While other manufacturers have felt the brunt of the global chip shortage Tesla has begun sourcing different silicon, according to The Verge, and rewriting its software to work with those new components. 

Additionally the company only recently began selling its popular Model Y in Europe and it's still relatively new to the Chinese market as well, giving it plenty of room for growth.

Of course, things aren't all rosy for Tesla. The company is still facing investigation by the National Transportation Safety Board here in the US. And it's only a couple of month removed from a massive recall of nearly 300,000 vehicles in China. Not to mention both its Roadster, Cybertruck and electric semi-truck are facing prolonged delays. 

Meet the Toyota C+walk. It’s a new three-wheeled electric scooter from the Japanese automaker designed to help people with limited mobility. While it shares some visual characteristics with battery electric vehicles like the Bird Three and Segway PT, its closest antecedent is the Concept-i Walk Toyota showed off back in 2017.

A removable lithium-ion battery allows the C+walk to travel about eight and a half miles on a single charge, after which it needs some two hours to recharge from zero to full. It can travel at a maximum speed of just over six miles per hour, though it’s possible to throttle it down to one mile per hour. Some of the more nifty features of the C+walk include an obstacle avoidance system. It will beep when it detects something on your path and slow down the vehicle if a collision is imminent.

Initially, the automaker envisions the scooter helping elderly workers travel across large facilities like warehouses, factories and airport terminals. In the future, the company hopes the Japanese government will certify the C+walk for use on public roads. Toyota dealers in Japan will start selling and leasing the scooter at the start of next month. It will start at ¥341,000, or just under $3,100 with the current exchange rate.

The California DMV has given both Waymo and Cruise permission to offer the general public autonomous vehicle rides — but only in certain parts of the state and under a set of conditions. Waymo applied for a deployment permit from the DMV back in January, while Cruise submitted its application in March. Now both companies only have to secure a deployment permit from the California Public Utilities Commission to be able to offer paid passenger rides in the state. 

Cruise's permit from the DMV would allow it to deploy five autonomous vehicles without a human driver for commercial services in designated parts of San Francisco. It can offer fully autonomous rides, because it was able to secure a driverless pilot permit from the CPUC back in June. The company's vehicles can only take passengers between 10 AM and 6PM, can drive with a maximum speed of 30mph and are not allowed to operate in conditions worse than light rain and light fog. 

Waymo's permit, on the other hand, requires the company to put human drivers behind the wheel. Its vehicles can operate in parts of San Francisco and San Mateo counties with a speed limit of 65 mph. Like Cruise's vehicles, they're not allowed on the roads in weather conditions worse than light rain and light fog. When it applied for a permit with the DMV, it said it will deploy hybrid Chrysler Pacifica minivans and all-electric Jaguar I-Pace SUVs, which will operation around the clock.

As the DMV's announcement notes, it has now approved three deployment permits in the state. The first company it approved was Nuro, which uses autonomous vehicles to make deliveries. Since Nuro's vehicles won't be shuttling human passengers, the company didn't have to secure a permit from the CPUC to start its operations. 

Cadillac has dropped quite an important feature from the 2022 Cadillac Escalade. According to Motor1 and Roadshow, the model won't come with Super Cruise, GM's hands-free driver-assistance technology. A spokesperson from the brand has confirmed to the publications that the Super Cruise would be "temporarily unavailable at the start of regular production," though they expressed the possibility that it would be available for vehicles manufactured later on. The spokesperson also revealed that the reason for this change is none other than the global chip shortage born out of the COVID-19 pandemic.

Cadillac's whole statement reads:

"Super Cruise is an important feature for the Cadillac Escalade program. Although it's temporarily unavailable at the start of regular production due to the industry-wide shortage of semiconductors, we're confident in our team's ability to find creative solutions to mitigate the supply chain situation and resume offering the feature for our customers as soon as possible."

The company also told Roadshow that it was only able to build "a few" CT4 and CT5 sedans scheduled for release this year with the capability to use Super Cruise. It had to postpone the full launch of its driver assistance system in the sedans until model year 2022, which will start shipping next year. 

The global semiconductor shortage has had an extensive effect on the tech and auto industries. GM, Cadillac's manufacturer, had to suspend production at all but four of its North American factories due to supply constraints. Nissan, Ford, BMW and Honda had to cut vehicle production, as well. In Ford's case, it led to the delay in shipments of the Mach-E electric vehicle.

GM has big plans for Super Cruise and previously announced its plans to bring the technology to 22 vehicles by 2023. It's unclear if these delays and adjustments caused by the chip shortage would affect the timeline it set for itself.

Swiss company ABB, which supplies EV chargers to Ionity and Electrify America, has unveiled what it calls the "world's fastest electric car charger," Reuters has reported. As its name suggests, the Terra 360 has a 360 kW capacity, meaning it could fully charge a (theoretical) EV in 15 minutes. More realistically, it can charge four vehicles simultaneously, saving space at charging stations. 

The Terra 360 isn't the most powerful charger by much, as companies like Electrify America, Ionity and EVGo have been using 350 kW chargers manufactured by ABB and others since at least 2018. However, it's the "only charger designed explicitly to charge up to four vehicles at once," the company said. "This gives owners the flexibility to charge up to four vehicles overnight or to give a quick refill to their EVs in the day." They also have a relatively small footprint, allowing installation in small depots or parking lots. 

There aren't a lot of EVs that can handle that kind of charge. The fastest-charging EV available is Hyundai's Ioniq 5, which supports DC fast-charging at up to 350 kW, in theory. The only two approaching that are Porsche's Taycan, with 270 kW of charging capacity and the new Lucid Air, which allows for up to 300 kW fast-charging. Tesla's Model 3 and Model Y EVs can charge at up to 250 kW. 

Such high charging levels aren't necessarily great for an EV's battery. Porsche, for instance, has a battery preservation setting on its Plug & Charge Taycan feature that lowers voltage to 200 kW from the maximum 270 kW allowed — so it's essentially acknowledging that faster charging degrades the battery. On top of that, extreme charging levels don't necessarily save you much time, as Car and Driver found. Tesla recently promised to upgrade its own Supercharger V3 network from 250kW to 300kW. 

ABB's new chargers will be able to add 100 km (62 miles) of range in less than three minutes. They'll arrive in Europe by the end of the year and start rolling out in the US and elsewhere in 2022.

Honda builds much more than cars and trucks — power equipment, solar cells, industrial robotics, alternative fuel engines and even aircraft are all part of the company's production capacity. On Thursday, Honda announced that it is working to further expand its manufacturing portfolio to include Avatar-style remote telepresence robots and electric VTOLs for inter- and intracity commutes before turning its ambitions to building a fuel-cell driven power generation system for the lunar surface. 

For its eVTOL, Honda plans to leverage not only the lithium battery technology it's developed for its EV and PHEV vehicles but also a gas turbine hybrid power unit to give the future aircraft enough range to handle regional inter-city flights as well. Honda foresees air taxis as a ubiquitous part of tomorrow's transportation landscape, seamlessly integrating with both autonomous ground vehicles and traditional airliners (though they could soon be flown by robots as well). Obviously, the program is still very much in the early research phase and will likely remain so until at least the second half of this decade. The company anticipates having prototype units available for testing and certification by the 2030s and a full commercial rollout sometime around 2040. 

Honda will have plenty of competition if and when it does get its eVTOLs off the ground. Cadillac showed off its single-seater aircar earlier this year, while Joby (in partnership with NASA) already has full-scale mockups flying. In June, Slovakian transportation startup, Klein Vision, flew from Nitra and to the Bratislava airport in its inaugural inter-city flight — and then drove home after the event. But building a fleet of flying taxis is no easy feat — just ask Bell helicopters — and we're sure to see more companies drop out of the sector before eVTOLs become commonplace.

Honda reps also discussed the company's future robotics aspirations during a media briefing on Wednesday. The company envisions a future where people are unencumbered by space and time, where telepresence robots have visual and tactile acuity rivalling that of humans. Rather than hopping on a plane to inspect remote factory floors or attend product demonstrations in person, tomorrow's workers may simply don VR headsets and step into the body of an on-site humanoid robot. 

The company announced that it wants its Avatar Robot — a newly refined iteration of the Asimo (above) — put into practical use in the 2030s and will conduct technology demonstration testing by the end of Q1, 2024 in order to meet that goal. But before that happens Honda reps noted that the company has work to do downsizing the robot's hand hardware and improving its grasping dexterity.

JAXA/Honda

Honda also has big plans for its space ventures including working on ways to adapt its existing fuel cell and high differential pressure water electrolysis technologies to work on the lunar surface as part of a circulative renewable energy system.

This system would use electricity gathered from renewable energy sources (like solar) to break the molecular bonds of liquid water, resulting hydrogen and oxygen. Those two elements would then be run through Honda's fuel cell to generate both electricity and supply the lunar habitats with oxygen for breathing and hydrogen for rocket fuel. 

The company also hopes to utilize the more-nimble Avatar hands its developing as manipulators on a fleet of remote controlled lunar rovers which will perform tasks on the lunar surface rather than subject astronauts to the moon's many dangers. Honda has partnered with Japan Aerospace Exploration Agency (JAXA) and began joint research into both of these systems in June.

Compared to what we were driving just a decade ago, today's connected cars and trucks are practically computers on wheels. From content streaming infotainment systems to the background processes that interpret sensor data and power the advanced driver assist features, software has become a fundamental component in modern vehicles. To better manage those countless lines of code, GM announced on Wednesday that it has developed an end-to-end software platform, dubbed Ulfiti (rhymes with "multiply").

GM's latest vehicles already enjoy features like OTA software updates and on-board internet connectivity thanks to the company's Vehicle Intelligence Platform (VIP). the Linux-based Ulfiti is designed to sit on top of that existing architecture and serve as a central hub for select software systems, separating them from the vehicle's core operations. 

"In all of the embedded controllers, we refactored them and extracted the software from the hardware out of them, making them available to our SOA layer," Scott Miller, Vice President of Software Defined Vehicle. at General Motors, said during a recent teleconference. "Basically we're abstracting them and making them available for a powerful hub for all the vehicle's systems."

"Then we're adding this service oriented layer on our high performance computing that we have in the vehicle for infotainment and safety," he continued. "And we're going to organize those abstractions as services."

This will enable GM to more quickly develop and deploy updates, new features and apps to customers. In essence, Ultifi will serve a similar function as Android does on smartphones — an API layer sitting between the underlying hardware and the end user. GM did note that Ultifi will run in conjunction with existing automotive OSes, such as Android Automotive, which GM announced in 2019 it would begin supporting. 

"Android Automotive is a certain subset of functionality in the car," Darryl Harrison, GM's Director of Global Product Development, explained. "Ultifi is more of an umbrella overall strategy. Some vehicles will have Android Automotive and some will have other infotainment apps and services."

In essence, GM wants to treat your vehicle like a rolling smartphone, offering users continuous OTA updates, cloud-based personalization options that drivers can transfer between GM vehicles, and smart home connectivity. The company is also considering pushing out various safety and comfort upgrades through via OTA, such as using the vehicle's onboard cameras to automatically engage the child locks when they detect children in the back seat or remotely closing the vehicle's sunroof if you parked outdoors and the weather forecast calls for rain.  

GM is also considering using Ultifi to offer subscription services to users, such as on-demand Supercruise that drivers can enable on long road trips but cancel once they reach their destination. Ulfiti could also allow for improved V2V (vehicle to vehicle) and V2X (vehicle to everything) applications including near-real time traffic and road hazard updates. Expect to see Ulfiti in select GM vehicles — both internal combustion and EV — starting in 2023.            

Another major automaker has revealed plans to move entirely to electric vehicles within the next decade. Rolls-Royce is the latest one to make the pledge, following other luxury brands such as Jaguar, Lincoln and Bentley.

Spectre, Rolls-Royce's first EV (and one that sounds like it's rolling off the set of a James Bond film), will arrive in the last quarter of 2023. The BMW brand plans to start testing the vehicle soon, according to Reuters. Rolls-Royce teased the EV in some images, but it literally kept the Spectre's design under wraps.

Rolls-Royce

Rolls-Royce CEO Torsten Muller-Otvos said that by 2030, the automaker "will no longer be in the business of producing or selling any internal combustion engine products." Sibling brand Mini has made a similar pledge. Parent company BMW has not set a date for making a full switch to EVs, though it aims to move half of production to electric models by the end of this decade.

As promised, Jeep has detailed its first Grand Cherokee plug-in hybrid. The company has confirmed the Grand Cherokee 4xe will arrive in North American dealers in early 2022, and will sport more capabilities than you might have expected. The estimated 25 miles of all-electric driving (440 miles total) won't necessarily cover your entire commute, but Jeep is promising a rough-and-ready PHEV that can climb hills without touching the 2.0L turbo gas engine. You can also drive in a full hybrid mode for peak performance and an "eSave" mode to preserve the 17kWh battery for later.

You can also expect new technology inside, such as 10-inch front and rear passenger displays with built-in Fire TV — your kids can stream Prime Video in the backseat. The driver, meanwhile, gets a 10-inch display with a much faster Uconnect 5 platform that supports over-the-air updates.

The 4xe and its regular counterparts are improved off-roaders with semi-active damping for air suspension as well as a front-axle disconnect when the SUV senses it doesn't need all-wheel drive. You'll also get semi-autonomous help through an optional Active Driving Assist system that takes over so long as your hands are on the wheel and your eyes are on the road. Jeep is promising a 6,000lbs maximum towing capacity.

Jeep hasn't divulged pricing for the Grand Cherokee 4xe, although it will be available in increasingly loaded Limited, Trailhawk, Overland, Summit and Summit Reserve editions. It's already safe to say this is an important vehicle for the brand, though. Parent company Stellantis is racing to catch up with rivals in electrifying its vehicles, with plans for a fully electric version of every SUV by 2025. The plug-in hybrid is a critical first step in that direction.
