Yeah, that's the thing that kind of drives me up the wall, seeing people drive a TINY amount just because they didn't think of walking. We have a couple of fast food places literally across the street from work and I've had people offer me a ride back. I'm like, you know it's actually faster for me to walk back in the building than to get a ride from you and wait for you to find a place to park, right?
The one thing that I miss having a car for is buying larger appliances. It's kind of a PITA to have Best Buy or whoever drive something up to your house. That being said, I don't buy large appliances terribly often. As for the freedom angle, one's freedom to theoretically drive to Portland (or insert next-door city here) on the weekends is more than outweighed by the fact of having to make car payments every month. Also, even if it does take an hour to take a bus that goes across the metro area, it's not like that time is just lost - thanks to not having to pay attention to the road I can, for instance, fire up my laptop and work on stuff on the way there. Or listen to podcasts. Or do some sort of necromantic combination.
