American auto makers are responding more rapidly than ever to the wants of American drivers.So you can have your dream car soon in your driveway.When you drive down the interstate highway,you can set the cruise control at the speed limit,then listen to Mozart,while the kids are in the back seat watching“Rugrats”on the built—in television.Then you glance at the screen of your personal computer,docked in the dashboard.
You say“map,”and a detailed route to your destination flashes on-screen.Then you say“traffic,”and you see a live video of the traffic flow two miles ahead.If it looked congested you’d say“reroute”and the computer would offer several alternatives.
There’s no need to reroute today,but as you listen to your voice—synthesized e-mail,you’re distracted from the tractor—trailer that pulls into your lane ahead.Your car senses it,and the cruise control automatically decelerates to maintain proper highway space between you and the truck.
It used to take up to six years to bring a car from concept to reality.
