700 MILES, hands-free!

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 southbound from Chicago, on Interstate 57 in Illinois.
