700 MILES, hands-free!

摘要

GM's Super Cruise turns Cadillac drivers into passengers in a well-engineered first step toward greater vehicle autonomy. Two sunny days in late September, a state-of-the-art luxury sedan, and good company make for a potentially great road trip. But this one was special. "Pretty remarkable that we've already driven about 500 miles without either of us touching the steering wheel; I'm impressed," I noted to co-driver Sam Abuelsamid, as we headed south-bound from Chicago, on Interstate 57 in Illinois.
