Is not that they are responsible for like 95% of accidents (with women and senior citizens making up the rest)
Is not that they always have that deer in the headlights look
Is not that they make lane changes without looking or signaling
Is not that parking lots are their kryptonite (anyone who's driven with me knows that this is true for me as well)
IT IS THAT THEY HAVE NO FUCKING CLUE THAT THEY ARE DOING SOMETHING WRONG. They are oblivious to their awful driving, and hence have no chance to ever improve. In their minds their driving is 100% a okay.
