The Blinker

Doesn't it drive you crazy when somebody in front of you forgets to turn off their blinker?  They could drive on for hours and be oblivious to the constant flash of the blinker.  Don't most cars make that annoying tinking sound when the blinker is on anyway?  What are you deaf?  Come on blinker guy, turn off that annoying little turn warning that you obviously don't know how to use.
