But you blame W if the guy in front of you leaves his left turn blinker on.
I know. Its great isn't it? Just blame W or BO and you no longer have to figure out which particular A-hole to blame. You have a ready made diatribe.

By the way, on a seriouser note, I figured out why that happens.
The blinker switch requires X amount of travel in the steering wheel in order to click off, as a car gets older the little switch wears so it requires more travel to flick the turn signal off.
The reason it happens mostly on Left turns is that we drive on the right so right hand turns are always tighter than left hand ones and require more movement of the wheel.
The reason it seems to happen more often to older people is that while the blinker has an audible tone, it is fairly faint, and the older you are, the worse your hearing gets so you are less likely to hear the sound.
Its Jonny Carson's joke. When you turn 65 five you back out of the driveway, turn on your right blinker, and never turn it off.
