Almost done with my 3rd year of mostly full time bike-commuting, estimate 180 days/year x 11mi rt x 3 yr ~ 6K miles, no commuting injuries or accidents that I can recall. (but who knows maybe head trauma made me forget accidents with head trauma?)

My commute consists mostly of straight, wide suburban arteries, with straight, wide bike lanes and buffer-striping, and good visibility. The only touchy part is going under an interstate (and negotiating with all the cars that have to cross the bike lane into right-turn-lanes for the entrance ramps). But I am always hyper-aware there and have never had any problems.

One close call where I have a right turn followed by a quick left, I didn't sufficiently look around when I moved left, fortunately the guy in the pickup behind me was paying better attention. I didn't even realize I was so stupid until he slowly passed me on the right and said out the window (very calmly) "That wasn't very smart".

Oh yeah another close call when I was going through a residential intersection, I had right of way, car on the left had a stop sign. It started to move at the same time a truck was coming towards me in my street, the truck panicked and swerved almost right at me, but recovered back into his lane.
