The empty highway stretches straight out to the horizon, so I take a moment to peek at the electronic display down in the car’s center console. I read out the numbers on the screen swiftly and glance back to the windshield, when I see ... nothing. A dense fog has swallowed the roadway, and I am driving blind. Before I can feel for the foot brake, an unmistakable warning—a brake-light red rectangle—flashes onto the windshield. Without another thought, I slam hard on the pedal, cursing loudly. My vehicle comes to a hasty halt as a disabled car emerges abruptly from the murk dead ahead.
Before I can even exhale, bright lights burn all around, and laughter rings out incongruously through the passenger cabin. I remember suddenly that I’m sitting inside the VIRTTEX (VIRtual Test Track EXperiment) driving simulator lab at Ford’s Research and Innovation Center in Dearborn, Mich. The big, egg-shaped simulator dome enables specialists there to conduct driving tests under totally safe but highly convincing virtual-reality conditions. The disembodied mirth on the intercom is the control-room technicians having a chuckle over my brief discomfiture.
