Cadillac's Super Cruise — look, Elon, no hands!

Cadillac is about to start selling vehicles with an autonomous driving mode and TechCrunch got an early look at the technology in a production car. "Wait for the green light and let go," the Cadillac engineer instructed. That's it. The car was driving itself. I, the person behind the steering wheel, was no longer the driver. Cadillac's Super Cruise system was driving. The 2018 Cadillac CT6 sped along U.S. 23 under the direction of Super Cruise. Traffic was light and the weather was perfect. The system held the Cadillac sedan in lane and responded appropriately to traffic. I spent an hour on the expressway and touched the steering wheel and pedals only a few times. Super Cruise made the drive boring. I think that's the point. Here's how it works Super Cruise is available once the driver navigates the vehicle onto an expressway. When ready, a little icon is displayed by the speedometer and the driver hits a button on the steering wheel to switch it on. Once the light bar on top of the steering wheel turns green, the driver can let go. Super Cruise is driving.This steering wheel light bar is key to the operation. When green, the driver knows Super Cruise is in control. Blue means the driver interrupted the system to change lanes and red means Super Cruise needs the driver to confirm they're paying attention and not checking Twitter. When active, Super Cruise controls the steering and speed, but again, only on an expressway. This is done through onboard sensors and using GPS and mapping data. GM employed GeoDigital, a startup in GM Venture's portfolio, to map 160,000 miles of expressways in the U.S. and Canada. The car company then used Super Cruise-equipped vehicles to test each mile. This combination of onboard systems combined with map data makes the system feel polished and sophisticated. During my admittedly limited time in the vehicle, the CT6 precisely held its position in the lane and confidently handled sweeping curves at speed. There was no wiggling or squirming — from the Cadillac or myself. The car was in control, and I felt safe. Although the driving conditions were perfect for my test ride, during adverse weather, the system will work normally until one of the key systems is unable to operate.

These are the fastest-selling new cars of 2024

Automakers finally appear to be back on their feet after a few years of severe instability, but that hasn’t helped all of them in the sales department. iSeeCars recently released its study on the fastest- and slowest-selling new vehicles and found that some companies are moving vehicles off dealersÂ’ lots at more than twice the pace of others. Toyota was the fastest-selling new car brand between October 2023 and March 2024, moving vehicles in an average of 39.6 days. Surprisingly, Alfa Romeo came second, averaging 41.8 days on the market. Last year, we saw a list of the fastest-selling individual nameplates overall, as opposed to this study that's ranked by brand. Fastest-selling new cars of 2024 Toyota: 39.6 days on the market Alfa Romeo: 41.8 Cadillac: 43.4 Honda: 44.2 Jaguar: 44.4 Kia: 47 Hyundai: 47.1 Subaru: 49 BMW: 49.1 Mazda: 53.1 The brands moving inventory the fastest show a strong value and desirability for buyers. iSeeCars executive analyst Karl Brauer noted, “Fast-selling brands like Toyota and Honda represent mainstream consumers seeking maximum value for their new-car dollar. Conversely, high-ranking luxury, low-volume brands like Alfa Romeo, Cadillac, and Jaguar reflect both their limited supply as well as high demand from affluent buyers willing to snap these models up shortly after they arrive on dealer lots.” Of course, there is no light without darkness, and on the other side of the list are a handful of brands struggling to move inventory. Lincoln was the slowest-selling new car company, with an average of 82.6 days to sell. Infiniti was close behind at 79.8 days, and Buick took an average of 79 days to move units. iSeeCars noted that new EVs take much longer to sell than their hybrid counterparts, at an average of 70.6 days on the market in March 2024, compared to just 49.5 for hybrids. Some of the fast-selling new brands also made the used car list. Used Hondas sold the fastest, only sitting on dealersÂ’ lots for an average of 26.1 days. LexusÂ’ used cars sat for 26.3 days, and Toyota moved its used inventory in an average of 27.4 days. By the Numbers Green Alfa Romeo Cadillac Toyota Car Buying

Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.
