Related to bike lanes, I just posted a thread with a link to a great column by Bob Mionske about door zones and bike lanes. He points out that it is often safer to ride to the left of a bike lane in order to avoid being doored. This is a big issue that I have with some of the roads in my town that were retrofitted -- restriped to narrow the car lanes and add bike lanes -- while on-street parking is allowed and in fact is heavily in demand.
