Your proposal is exactly how self-driving cars were created:

"Back in 1995 the goals for self-driving cars were more modest than they are today. They weren’t called autonomous, but self-driving. And there was no plan to have cars drive themselves on city streets, just on freeways and highways — on the Interstate. The plan was to bury cables in the pavement over which all the cars would drive and communicate with each other and with the road, itself. The goal was to fill the road with cars driving at the speed limit, spaced precisely one meter apart" [0]
