While I get where you're coming from, and I agree that most transit drivers are pretty darned good, they have their moments too -- I watched a bus drive into a car on Friday as both were making right turns. The bus driver either forgot that it was two right turn lanes (he was in the left-hand right turn lane..) or underestimated how much his rear would swing in behind his front end. Either way, the bus was clearly at fault, and the car was squashed. Had a bicycle been in that particular position, all would likely have been well. but in a narrower situation, even a bike could have been squeezed or worse.
