Who: The guy who accompanies his car’s turn signal with hand signals.
Why: It’s unnecessary, it’s pointless and it’s distracting. When I’m driving, I take note of a car’s turn signal with an almost perfunctory sense. The last thing I need is some hipster sticking his hand out and making some sort of – what the hell is that? Gang signs? It takes my eyes off the road and breaks my concentration and all because some doofus is either being extremely overcautious or ridiculously retro.
How I justify it: It’s not 1915 and you’re not driving a Model T, tooltime! Signal like the freakin’ owner’s manual tell you to.
