Cadillac Super Cruise, a hands-off review

Cadillac Super Cruise won't let you eat breakfast behind the wheel, climb in the back seat or any of the other stupid human tricks displayed on YouTube by Tesla owners. It even won't allow the car to change lanes on its own, like Tesla Autopilot. But it's a big step on the road to full autonomy, a huge convenience on long-distance road trips and a substantial technological triumph for Cadillac. In the simplest terms, Super Cruise is a lane-centering enhancement to adaptive cruise control (ACC). But Super Cruise is anything but simple. Its technical complexity — hence its long delay after first being unveiled five years ago — belies its straightforward operation and intuitive user interface, which I discovered on an almost 750-mile, 11-hour drive in a 2018 Cadillac CT6 between Dallas and Santa Fe to test the system. LOADS OF LIMITATIONS First, let's dispense with the details and disclaimers. Super Cruise is standard on the 2018 CT6 Platinum and a $5,000 option on other trim levels. Because Super Cruise is supported by OnStar — an OnStar operator will call to find out if first responders need to be sent in a worst-case scenario — a three-year OnStar Super Cruise Package is included with the system. Super Cruise has loads of limitations that are probably more concerning to GM's legal counsel than they were to me during my long drive. Some are no-brainers, such as not for use in construction zones or for driving on the shoulder. But the system can also be stymied by adverse weather, poor visibility and faded lane markings. Super Cruise only works on freeways with on and off ramps and a center divider. ACC and forward collision warning also need to be engaged, and the system's cameras and radar sensors can't be obstructed. To keep drivers from looking away from the road for too long — and to keep the system active — an infrared camera on top of the steering column keeps an electronic eye on the driver's seat. GM has over 100 patents alone on this Driver Attention System, including an algorithm that triangulates the nose, eyes and ears in case the camera can't see through sunglasses to make sure you're not nodding off. In addition to the car's visible sensors, another major component of the system is something you don't see: mapping software. But not the kludgy kind that powers in-dash navigation systems.

What to do if you run out of juice in your Tesla Model S

After writing about their Tesla Model S running out of juice on the side of the road between Las Vegas and Barstow, CA recently (read about it here), the fine folks at Teslarati figured they had some 'splainin' to do. The brief explanation is headwinds. Yes, headwinds. A Model S has about 10 miles of range even after it shows a big fat "0" on its dash. Thankfully, the drivers took notes about what to do if your Model S is about to shut down like C-3PO in A New Hope. Step one is to know that the EV has about 10 miles of range (maybe 20) even after it shows "0" on its dash. Once that distance is used up, it's time to pull the car over, and even then there is enough reserve juice to power the screen for a half hour. After that, all that works are the door handles and the flashers. So, before everything goes completely dark, it's best to remember to put the car into "tow mode" and get it into neutral so that the EV doesn't have to be jumpstarted just to get it onto a truck. Also, once the Model S has been recharged from empty, it needs to be powered off in order to reset the system and not keep it in "depleted power" mode. Now you know. The way Teslarati learned all of this was that, after using a Las Vegas supercharger to give their Tesla Model what they thought would be about 240 miles worth of range for the 160-mile drive, the car unfortunately provided them with just 157 before shutting down. The culprit was a sand storm that sent 35-mile-per-hour headwinds (and probably a bit of grit) into the car as it maintained a 75-mph cruising speed. Teslarati also said elevation changes were part of the problem. Las Vegas and Barstow are both about 2,200 feet above sea level, but there are a bunch of hills in between, and we guess the declines giveth less then the inclines taketh away. Happens to the best of us.

2016: The year of the autonomous-car promise

About half of the news we covered this year related in some way to The Great Autonomous Future, or at least it seemed that way. If you listen to automakers, by 2020 everyone will be driving (riding?) around in self-driving cars. But what will they look like, how will we make the transition from driven to driverless, and how will laws and infrastructure adapt? We got very few answers to those questions, and instead were handed big promises, vague timelines, and a dose of misdirection by automakers. There has been a lot of talk, but we still don't know that much about these proposed vehicles, which are at least three years off. That's half a development cycle in this industry. We generally only start to get an idea of what a company will build about two years before it goes on sale. So instead of concrete information about autonomous cars, 2016 has brought us a lot of promises, many in the form of concept cars. They have popped up from just about every automaker accompanied by the CEO's pledge to deliver a Level 4 autonomous, all-electric model (usually a crossover) in a few years. It's very easy to say that a static design study sitting on a stage will be able to drive itself while projecting a movie on the windshield, but it's another thing entirely to make good on that promise. With a few exceptions, 2016 has been stuck in the promising stage. It's a strange thing, really; automakers are famous for responding with "we don't discuss future product" whenever we ask about models or variants known to be in the pipeline, yet when it comes to self-driving electric wondermobiles, companies have been falling all over themselves to let us know that theirs is coming soon, it'll be oh so great, and, hey, that makes them a mobility company now, not just an automaker. A lot of this is posturing and marketing, showing the public, shareholders, and the rest of the industry that "we're making one, too, we swear!" It has set off a domino effect – once a few companies make the guarantee, the rest feel forced to throw out a grandiose yet vague plan for an unknown future. And indeed there are usually scant details to go along with such announcements – an imprecise mileage estimate here, or a far-off, percentage-based goal there. Instead of useful discussion of future product, we get demonstrations of test mules, announcements of big R&D budgets and new test centers they'll fund, those futuristic concept cars, and, yeah, more promises.
