I got my license within 6 months of my 16th birthday. I haven't had a car since I was 22 (which was never technically mine, it was my dad's, I just drove it). I've been a licensed driver for 14 years, I've been carless for 8 of those. I've lived in the DC area since 2004, and I've never had a car here. The brakes on mine failed about 3 days before I moved here, which was convenient, since I hadn't planned on bringing it. I still have a license (MD-issued), because occasionally I do drive. I have memberships to ZipCar and Car2Go (which is a better service, because cars don't have to be returned to their point of origin, but ZipCar has bigger vehicles), but mostly I use Metro and BikeShare (and taxis and friends who have cars). I like to brag about my flawless driving record (no accidents, no speeding tickets, never been pulled over outside of a situation where they were pulling everyone over), and then my friends remind me that this is because I don't drive. But I'm also a good driver, which people often remark on when they do get in a car I'm driving (I can even drive a stick, if you don't care about your transmission still being there when we're done). I've known several people who don't drive and are bad at it (of course, I've known several bad drivers who do it every day, too) or afraid of it, and some who have even had their careers negatively impacted by their unwillingness to drive. Sometimes I feel bad because I can tell you 15 ways to get to your destination in DC, but I have no idea where you should park once you get there.
@Mal*Pal Or they assume that you just want this job to pay the bills and will quit as soon as you can, not realizing that sometimes you are legit looking to change fields.
