The golf cart thing I think could be done without authoritarianism, just legalize city cars. Lots of people who can't drive or drive old crappy cars could get a brand new 2500 dollar electric city car that runs off of tiny batteries and putt around town with that. I am loathe to buy another whole full power car, but I'd be eyeing a city car pretty carefully. No gas, just something that'll get me to the supermarket and back? Sounds like a good deal to me.
