#Semi-autonomousDriving

Despite receiving high praise as one of the most advanced driving aids on the market, Cadillac’s Super Cruise isn’t perfect. Automotive writers frequently debate whether it’s superior to Tesla’s Autopilot, without reaching a consensus. Most experiences have shown Tesla to have the more hassle-free interface with Cadillac providing something that errs on the side of caution. Similarly capable, Super Cruise is more persnickety about where and when can use the system — not a terrible impulse, especially considering how all modern driving aids can be flummoxed by a little salt and snow.

However, one gripe we’ve repeatedly heard about Super Cruise was that the system sometimes didn’t make it clear why it isn’t operating. General Motors has identified the problem and says it plans to implement a fix, but it might only come with the next generation of the company’s semi-autonomous hardware.

Tesla CEO Elon Musk says a new chip aimed at improving its vehicles’ Autopilot features will be available in about six months.

However, if you’re hoping the automaker is preparing to light some candles and knock its vehicles up with legitimate self-driving technology, you’ll need to keep on wishing. During a string of tweets on Tuesday, Musk explained that the new chip would be a $5,000 extra for customers who did not purchase their cars with the “Full Self-Driving” package — an automotive claim that’s about as valid as Donald Trump’s hair or Elizabeth Warren’s status as a Native American.

Now that new car buyers have a decent selection of semi-autonomous driving systems to choose from, Consumer Reports felt it would be a good idea to put them to the test.

Expect to see much consternation expressed on Tesla forums. The rankings, which pitted Cadillac’s Super Cruise against Tesla’s groundbreaking Autopilot, Nissan’s ProPilot Assist, and Volvo’s Pilot Assist, shows GM’s luxury marque in the lead.

What propelled Cadillac’s system to the top of the heap? The same element that gave Tesla’s system a black eye two years ago: safety.
