This would fix the three major stumbling blocks to electric cars: recharge time, range, and cost. Cars would recharge while driving along the road, giving them infinite range and zero recharge time. They would no longer need large batteries to give them range, just smaller ones to drive around while off the electrified roads. This would bring down the cost of an electric car.
The electricity for the roads can be generated using new design nukes, which have low costs of generated power. This should give the cars per mile costs lower than gasoline fuel.
As an electrical engineer, specialized in power systems, I would like to hear more about how you think this works.
