A popular pet peeve for some of us is people not using their turn indicator while driving. I admit, it annoys me a lot when people don't signal their intent at all, or if they turn on their blinker during the turn (what's the point?). How many times do we hear ourselves saying in the car, "What the heck are they doing?!?" - or a similar version but chock-full of expletives? We may say this regarding other people and businesses when we are not in the car too...
