Lived in Paris for years but wanted to go to my native Normandy 90 minutes away by car often, with friends (so train is uneconomical, and whatever): I love car free cities just as much as I love cars, but I feel they always miss the massive parking space at the periphery. Those have to be free one day, and truly understood and desired, so we can sort of mix the intra city metro/bike, the intra regional car, and maybe the rest by train (but again, train multiply cost for a group when car divides it so hard to choose).
Now I live in Hong Kong, bought a 1998 Porsche 911 that guzzled gas and spat good smoke, that cost me so much in eco tax and gas tax (the same thing, really) for so little use I gave up and am car-free now :D
Cant wait for massive electric cars adoption where the discussion will move away from how we murder the world for fleeting amusement, and back to transport convenience and pleasure to drive. But Im sure we ll find problems with Lithium mining or whatever.
