THE FUTURE DF THE CAR

摘要

"YOU CAN GRIP the wheel very loosely," the BMW engineer told me as I settled into the driver's seat of the BMW Track Trainer. "Very loosely, to get a feel for how it is turning. But do not touch the pedals." I detected in his tone an "unless" on the way. "Unless I yell stopl In which case you should grip the wheel tightly and stomp on the brakes." He smiled. "Shall we go?"With that, I released the brake and sat back as our unassuming 3 Series sedan accelerated of its own volition down a short straightaway, whipped ably into a right-hander, and then moved wide to set itself up for a fast curve to the left. I was, as instructed, holding on ever-so-slightly, but that felt weirder than just watching the wheel turn on its own, as if I were sitting in the lap of a ghost driver-which is pretty much what I was doing.
