Wouldn't wet glass be dangerously slippery?
I've thought about piezoelectric road surfaces, but I'm not sure how much electricity you could get there. I've also wondered about cars with magnets that induced currents... It's an interesting challenge.

There are ways to make glass non-slippery - but all increase costs, and most would reduce light transfer, too. There are lots of things wrong with this idea, I admit. I still like the fact that they are thinking big.
Piezoelectrics would be an interesting way of generating more power from smart roads, too.
