True. It would definately take time. They do have to re-pave roads pretty often though, so it does seem plausible for it to be worked into existing roadways.. But you're probably right, seperate lanes or whatever would be the way to go, and that would solve the problem of all the millions of used cars that won't have the system.
It's exciting, really. Knowing that I'll most likely be alive when big changes like this come about is really cool. 🙂
