I grew up near The Villages. Really crazy to see such a cool innovation basically coming to my home town. That being said, I don't know if self-driving cars are the right approach in that market. Have you considered self-driving golf carts? =P

(for those of you who don't know, The Villages has arguably more miles of golf cart paths than highways, and all shopping plazas have golf-cart sized parking spots, so most of the retirees cruise around on their carts)
