How much distance have drivers covered using GM's Super Cruise hands-off driver assistance system? Enough to drive from the Earth to Saturn, which is a comparison that GM probably wishes we hadn't used. The company has installed its tech in close to a million vehicles, and it is now offered on 23 different GM models from Bolt to Escalade. 2,100 Trips To The Moon And Back GMCOne billion miles. More than half the distance to Uranus. That's the milestone that Super Cruise hit this week. That's impressive for a feature that has only been on the market for eight years, and the distance is now ramping up faster than ever.GM said that nearly half of the total distance was added in just the last 12 months. That's 485.9 million miles in the last year, more than a million miles of hands-off driving every day. 7.1 million hours of the car doing most of the driving and 28.7 million trips. The figure still trails Tesla's claimed 8.6 billion miles for Full Self-Driving (Supervised), but it's not clear how many of those miles are hands-off.Super Cruise has been installed on almost 750,000 vehicles so far, and GM says its customers are really using it. More than 50% engage it at least once a week, and nearly 85% use it at least once a month. The number of daily users grew by 80% last year, as it gets installed on more and more new vehicles, and adds features like towing.They're also keeping it once the free trial expires. GM said that up to 40% of users renew their subscriptions, and it expects to have 850,000 users by the end of this year.GM's semi-autonomous system, which debuted in 2018 on the Cadillac CT6, lets the driver take their hands off the wheel in certain situations. On the nearly 400,000 miles of mapped highways, divided and undivided, it can handle most driving scenarios, including lane changes and passes, on its own. Eyes-Off Already Being Tested On-Road CarBuzz/Valnet/Nicole Wakelin Right now, the system requires drivers to watch the road. Starting with the 2028 Cadillac Escalade IQ, drivers won't even have to do that. The new eyes-off system is set to launch that year, and it may be the first of its kind to market.GM has already started testing this next-generation system on public roads in Michigan and California. More than 200 development vehicles will be driving in real traffic, though there will be a trained safety driver able to take over if the system isn't up to a task.In the shorter term, GM is about to update its voice assistant tech on cars going back as far as 2022. The built-in voice assistant on four million GM vehicles is about to be replaced with Google's Gemini AI assistant. The goal is to give customers "smarter, more proactive assistance in the vehicle." GM didn't say what extra vehicle functions this might give you, if there are any.After launching on the CT6 in 2018, Super Cruise first expanded to the Cadillac CT4 and CT5 before being added to the Escalade in 2021. It expanded to Chevrolet and GMC first in 2022 on full-sized pickups before being added to the Bolt EV shortly after. The first Buick to get the feature was the Enclave in 2025.
