On some freeways in my country, idiots have a habit of driving 2x the speed limit. Checking your blindspot at the time you started the maneuver is no guauantee it will still be empty a half a second later. The blind spot detector is pretty helpful IMO. Btw .. I don't understand what perfect world some people live in. Do you live in a world where programmers write bug free code every single time like they have been taught?
