I walk (although I sometimes get the bus to work if the weather is bad).

Of course, I am lucky enough to work in the centre of Edinburgh and live just a short distance away (about 30 minutes walk at a reasonable pace). It was Edinburgh's insane parking regulations that made me sell my last car a few years ago. I had to park it about 20-30 minutes walk away from the flat that I was renting at the time, and it got way too annoying (there were several times that I "lost" the car because I had forgotten where I had parked it).
