I almost got T-boned (in my car) yesterday by someone who either wasn't going to stop at a red light or didn't realize where the stopping point was (this is in a construction zone).

I saw my life flash before my eyes. Thank god it was only 2 miles from my house, or I would've had to stop and recompose myself.

If I run a light on my bike, I primarily endanger myself, and secondarily whatever drivers I scare the poop out of. Cars who run red lights primarily endanger others, since side impacts are much less protected than front-end collisions.

So if someone pulls the "cyclists don't follow traffic rules" etc on me I just shrug, say that I do, and that Darwin will take care of those who don't. It doesn't work the same for cars.

(Just to clarify - I don't run lights. Ever. Not even the ones I can't trip.)
