Actually, self-driving cars are the only proposed solution to automobile accidents and related deaths that seems like it might work. Laws don't work, education doesn't work, and even the safest, most careful drivers can and do have accidents. Let's be clear. In the US, at least, cars are not going anywhere unless costs become as prohibitive everywhere as they are in NYC. Even then, they're still not going anywhere (NYC still has a ton of cars obviously). I have no idea what making communities smarter means. What exactly are you proposing?

Generally he means addressing the problems "heavy car usage, not enough walking, and no safety for humans". Optimizing city design for people, and not for vehicles. This is generally done by increasing density, and requiring mixed-use buildings with commerce on ground level, and more public spaces and wider side walks, and dedicated lanes for bikes and public transportation.

Cars aren't going anywhere anytime soon in the US because sadly you can't function without one in the vast majority of places. It's far easier to implement this design philosophy for a growing city[1], but really hard to change the layout of a mature one, though it can be done thoughtfully [2].
