Imagine a world of self driving, electric cars. If the roads themselves powered the cars, the batteries in the cars could be much smaller, enough to get off these powered roads to the final ~10 miles and then back again. In terms of longer distance travel, instead of railways, we could have caravans of cars all going in the same direction that attach to each other powered by a single engine at the front with a larger more powerful engine with bigger batteries. These could all be arranged real time since everyone would know each other’s destinations, so individual cars could hop and off when they need to. I think it’s a great idea and could really change transportation.
