GM's Super Cruise Network Is Growing to about 750K Miles of Roads

The hands-free system will add the new compatible highways in North America via over-the-air updates through next year.

• GM's Super Cruise network will be accessible on about 750,000 miles of highways across the U.S. and Canada by next year.
• The hands-free-driving system currently works on about 400K miles of highways in North America, including some undivided sections and soon some minor ones.
• GM says the expanded compatibility is currently happening via free over-the-air updates; a few Super Cruise-equipped models are exempt.

For people who own a GM vehicle equipped with Super Cruise, the number of roads in North America that they can use the hands-free system on will double by sometime next year. That news comes today as the automaker is actively working to expand the Super Cruise network from around 400,000 miles of compatible highways to about 750,000 miles.

More Roads to Super Cruise On

When it launched back in 2017, Super Cruise began allowing drivers to travel on mapped divided highways without having to keep their hands on the steering wheel. Of course, staying attentive is mandatory. The network included about 200,000 miles over a year ago, and it has since doubled, adding some undivided highways too.

By the end of 2025, the amount of compatible roadways in the U.S. and Canada is expected to almost quadruple. Notably, those miles will also include some minor highways that stretch between smaller cities and towns. Currently, Super Cruise can automatically change lanes and even works while towing a trailer.

On most GM vehicles equipped with Super Cruise, the growing number of compatible roads are being made accessible via over-the-air software updates. While there's no fee for the expanded network, the company says the process won't be complete until sometime in 2025. Each vehicle will take about a month to update after GM's map adds the new roads.

GM Super Cruise

Gm nearly doubles its map of super cruise hands-free driving routes in north america.

General Motors (GM) has once again expanded its maps of routes that enable Super Cruise hands-free driving in North America. The American automaker now operates the largest hands-free driving network now that it has nearly doubled the mileage of available routes on the continent.

Super Cruise is a hands-free driver assistance feature introduced to the GM family of vehicles in 2017. It uses adaptive cruise control technology and car-connected services to navigate LiDAR-enabled map data using real-time positioning, cameras, and sensors.

The result is an EV that can control its own acceleration, braking, and automated lane changes while driving on compatible roads. GM states its vehicles have driven over 160 million miles with Super Cruise engaged to date, with zero accidents.

While the original Super Cruise map started relatively small, GM has continued to bolster the size of its network in the US and Canada as it expands the hands-free driving capabilities to 22 different models via over-the-air (OTA) updates.

In August of 2022, we saw GM expand its Super Cruise map to about 400,000 miles across North America , but today, it has announced its network has grown again, nearly doubling in size. Have a look at the comparison image below.

GM expands Super Cruise map to 750,000 miles

As you can see in the images above, GM’s latest Super Cruise map covers a significantly more significant portion of roads in North America, particularly in the eastern half of the US. GM shared that 750,000 miles of hands-free routes now available are equivalent to a one-way trip from Earth to the Moon or a round trip drive from New York City to San Francisco nearly 130 times.

Following the expansion, GM is hailing its Super Cruise network as the largest truly hands-free map in the industry. It is also the only one offering trailing capabilities using the ADAS feature. GM Vice President of ADAS Anantha Kancherla spoke to the network’s latest milestone:

GM is all-in on safely deploying Super Cruise as we make the technology available on more vehicles, more roads and for more people to enjoy. A key part of that is expanding the road network — in this case nearly doubling it again — with LiDAR mapped highways.  High precision LiDAR mapping gives us an operating domain where we are confident in Super Cruise’s abilities.

Additional major and minor highways are being added to GM’s Super Cruise network daily and will continue to become available to drivers through 2025. Most Super Cruise-equipped EVs will receive the expansion, aside from the Chevy Bolt EUV.

GM Expands Super Cruise Coverage

Hands-free driving will soon be available on 400,000 miles of mapped roads

General Motors is doubling the Super Cruise network to 400,000 miles of mapped roads in the U.S. and Canada. The hands-free Super Cruise active driving assistance system currently works on mapped divided highways, but it will soon allow compatible vehicles to use this feature on additional state and federal routes, adding divided and undivided highways. Super Cruise supports the driver to relieve fatigue and stress, such as on long highway road trips, automating some acceleration and steering functions.

Notable additions include U.S. Route 66, the Pacific Coast Highway (aka California’s state Route 1), Overseas Highway (aka U.S. Route 1), and the Trans-Canada Highway. 

The mileage expansion will be available later this year and will be delivered over the air at no additional charge on Super Cruise-equipped models, a GM spokeswoman told CR. These initial models use the Vehicle Intelligence Platform (VIP) and currently include the Cadillac Escalade , CT4 , and CT5 ; the GMC Hummer EV and Sierra ; and the Chevrolet Silverado . By the end of 2023, there will be 22 GM models with available Super Cruise.

Super Cruise stands out for its focus on mapped roads, rather than depending on the car to navigate as it goes, and for its effective direct driver monitoring. It stands apart in its ability to very clearly communicate to the driver via an illuminated steering wheel when the car is in control, when the driver needs to take over, and when the driver is in full control. The current Super Cruise system warns the driver with flashing LED lights on the steering wheel, and it can bring the vehicle to a gradual stop if the driver does not respond.

This news builds on the announcement earlier this year that GM would be introducing Ultra Cruise as an extension of the Super Cruise feature with the added capability of driving on city and subdivision streets and rural roads. Ultra Cruise will debut on the Celestiq electric car. 

Like Super Cruise, Ultra Cruise will still require the driver to be looking ahead. An inward-facing camera behind the steering wheel ensures that the driver’s eyes are watching the road. 

The automaker says Ultra Cruise will initially function on about 2 million miles of roads in the U.S. and Canada and that it will be able to follow plotted navigation routes, maintain following distance to vehicles ahead, obey speed limits, and react to permanent traffic control devices. Within the next two years, it will work on almost every paved road in the U.S. and Canada.

GM spokesperson Philip Lienert previously told CR that “Ultra Cruise works through the same basic sensor types as Super Cruise—it just has approximately 70 percent more of them, including integrated lidar behind the windshield.”

The addition of lidar with Ultra Cruise is a big deal. The technology uses light to pinpoint distances, and its accuracy makes it an integral part of many self-driving car prototypes. Lidar has traditionally been too expensive for widespread use, but prices are coming down, and more automakers are showing interest.

GM is preparing for another major expansion of its hands-free Super Cruise system

By 2025, the automaker says super cruise will be operational on approximately 750,000 miles of road in the us and canada, including more rural, back woods roads..

General Motors may be struggling when it comes to fully autonomous driving , but the company is still feeling bullish about the future of hands-free driving. Today, it announced plans to expand its Super Cruise advanced driver-assist system, which allows drivers to take their hands off the steering wheel on certain roads, to cover nearly double the number of miles it did before.

Today, Super Cruise is operational on 400,000 miles of road in the US and Canada. The company plans on adding around 40,000 miles of new roads every quarter over the course of two years, so by the end of 2025, Super Cruise will cover approximately 750,000 miles in the US and Canada.

Launched in 2017 with the Cadillac CT6, Super Cruise uses information from cameras and radar sensors embedded in the car, GPS data, and lidar mapping data to allow for hands-free driving and, in some cases, automatic lane changes. It pairs this capability with a driver-monitoring system that uses an infrared camera to make sure the driver is keeping their eyes on the road at all times in case Super Cruise needs to hand back control to the driver.

• Hands-free driving is becoming more popular — but is it safe?

For years, Super Cruise was limited to divided highways that GM had laser mapped and approved for use. But starting with its model year 2023 vehicles, the company started adding nondivided state and federal highways, which are sometimes called routes — main roads that connect smaller cities and towns. That includes popular roads like US Route 66, the Pacific Coast Highway, the Overseas Highway, and the Trans-Canada Highway.

GM says it will continue to add more routes and nondivided highways over the next few years to expand Super Cruise’s operational domain. According to David Craig, chief of maps at GM, these will include “two lane highways that are designed to connect the little towns, the more rural areas, the back woods areas where people take their RVs and campers and go hiking and hunting and camping.”

“the more rural areas, the back woods areas”

For its mapping data, GM contracts with a Michigan-based company called Dynamic Map Platform, which operates a fleet of vehicles that scan “every mile of road” using lidar laser sensors, Craig said. Those maps are then fed back into GM’s central system, which pushes out quarterly software updates to ensure each vehicle is operating with the most updated version of the map.

Super Cruise’s capabilities will remain the same, and the system won’t be able to handle any new driving scenarios, like traffic lights and four-way stops, said Jeff Miller, product manager for Super Cruise.

The company recently stopped using its “Ultra Cruise” brand , which was intended to be its big Tesla competitor, deciding instead to merge the team that was working on it with its Super Cruise division. Ultra Cruise was intended to cover “95 percent of driving scenarios” on over 2 million miles of road.

To be sure, GM says it is approaching the concept of hands-free driving as safely and cautiously as it can. Miller contrasts this approach with Tesla’s Full Self-Driving, which still retains its status as a beta product despite being available to over 400,000 Tesla owners in North America.

“We’re not going to beta test on our customers,” he said, “like some other competitors do.”

Still, GM is chasing Tesla in some respects. The electric automaker’s Full Self-Driving program is operational on local roads and residential streets and purports to handle more complex situations like roundabouts, traffic lights, and four-way stops. How well it handles these scenarios is open to debate, as regulators and safety experts continue to evaluate and study the technology.

What is clear is that dozens of people have died while using Tesla Autopilot, and at least one person appears to have been killed in a crash while using Full Self-Driving. Miller says that is not the case with Super Cruise.

“Our customers have driven Super Cruise completely hands-free 160 million miles,” he said, “and there has not been one accident attributed to Super Cruise.”

Which is not to say there won’t be an accident someday, especially as Super Cruise expands its map and becomes available to more customers. “I mean, there could be,” Miller said. “We designed the system as robustly as possible.”

GM’s Giant 400K-Mile Super Cruise Update Coming to Full-Size SUVs First

Been waiting for an excuse to take your new Escalade on a cross-country road trip? Here it is.

General Motors is greatly expanding its Super Cruise network to cover 400,000 miles of roads . It will now include some scenic routes as well, like Route 66 and the Pacific Coast Highway. It hasn't actually been loaded into any vehicles yet, but that's changing soon as the first recipients will be the automaker's full-size trucks. Yes, the land barges will appropriately be the first ones to get the automaker's latest hands-free driving tech.

If you're set to take delivery of a high-trim 2023 Chevy Tahoe or Suburban, a 2023 GMC Yukon Denali Ultimate, or most flavors of the 2023 Cadillac Escalade—including the very fun and loud Escalade V—then you'll have access to the latest version as soon as you get your car. If your truck is a little bit older, you'll get the update in "the coming months" over the air. No more putting a DVD in the center console and listening to the car make DSL noises—it's all wireless.

Any other vehicle on GM's VIP electrical architecture is also set to get the update. That means it will eventually come to the Cadillac CT4, CT5, and  Lyriq . The Chevy Silverado and  GMC Sierra will also receive it alongside future EVs. There is no precise timeline for that rollout, though. Keep in mind, the Cadillac Lyriq still doesn't have Super Cruise at all.

Super Cruise originally covered 130,000 miles of mostly interstates. The latest update doubles the size of the service's previously enhanced 200,000-mile coverage. The tech's closest competitor, BlueCruise from Ford, currently covers just 130,000 miles of roads. Keep in mind, GM has had a considerable head start in terms of development as it's been building Super Cruise's capability since 2017.

The next big step for the hands-free system is Ultra Cruise , which GM claims will be able to handle almost all driving situations from door to door . It's set to debut on the $300,000 Cadillac Celestiq , although it will eventually filter down to other models as well.
