As all my close calls with cars in the past year have come when I was using a bike lane, my tendency now is to avoid bike lanes and use side streets. The way they're laid out in my town is not very smart-- you're often in the door zone of a lot of parked cars. Also, there's no prohibition of parking in or otherwise blocking bike lanes here. So it's side streets a lot of the time, or taking a general traffic lane whenever I don't feel the bike lane is safe, which is most of the time.

But the conditions in every city are different, as are folks' risk tolerance...
