The road to the future
Visionaries of the past, such as Harley Earl, godfather of the concept car, figured that such an automated traffic-control system would require sensors or wires embedded in the road, which also places the financial burden on an infrastructure makeover. But what if cars could do most of the work in self-navigation? We're on the verge of being able to use GPS technology on a mass scale to triangulate from inexpensive Wi-Fi hot spots where cars are located down to the inch.
That would allow vehicles to parade down the highway and in congested areas in a conga line of bumper-to-bumper traffic moving in unison. There's a safety aspect, too. If one car hits the brakes when it senses black ice or other road hazard, the other cars around it can be warned.
