I am convinced that if I am following someone slow and am about to turn, using my signal ensures the slow person will stay in front of me and make that same turn. But if I fake to the other side, the slow car turns then I whip around, signal and make my turn and lose the slow bastard. BTW, fawkin conversion vans are the SCOURGE of the roadways!!! Slow pieces of shit can't manuever their way out of a paper bag, no less around the streets
