Hi Carfree folks,
We have an interesting situation in that my wife and I are lucky enough to be able to live in the UK (Oxford) and USA (Los Angeles). In the UK (where work dictates that I spend the majority of my time) we're 100% car free, and hire a vehicle if we really need it, perhaps twice a year e.g. for chrismas holiday travels etc. Otherwise, it is possible to be carless here in Oxford and not really notice. In fact, traffic and access for most commuting and town centre journeys are so slow by car that a significant number of people cycle, walk, or use public transport.
In LA, my wife has a car that she needs to get to work - a sensible, economical Honda Civic, not a gas guzzling SUV by any stretch of the imagination.
I'm almost car free in LA, and prefer to do most errands by bike (besides, its quicker for journeys of 5 miles or less). However, I have a restoration project in the garage - a 1967 MGB (small British convertable sportscar). I look at this as more of a rescue project that will eventually be a "luxury item" for infrequent fun trips, rather than an everyday car, but it does compromise my car free status...
Anyway, more power to the carfree folks out there!
