It's funny you should mention ZipCar. I use their service, and it's very convenient for me in some cases, but really it just reminds me of how obnoxious it is

It's funny you should mention ZipCar. I use their service, and it's very convenient for me in some cases, but really it just reminds me of how obnoxious it is to drive around the city (I live in Boston). Before I moved into the city, I never drove within it: it was always easier (and cheaper, considering the difference in parking prices) to park at one of the several T stations at the edge of the city and ride in. When I use Zipcar, I don't get that option. I usually get there faster than I would on the T, but the time on public transit is not wasted (I can read), while the time driving is. Unfortunately there are still things the T can't do, but I find the hybrid approach works well for me. The few occasions where I do drive only remind me of how well.
