We all drive selfishly or obnoxiously from time to time. But there’s another kind of driver who’s in a whole ‘nother league. The mark of a truly loathsome driver is one who doesn’t even realize that he/she is blocking others or causing traffic jams or whatever. They’re so fixated on their own needs or frustrations that it never even occurs to them that they’re making things difficult for others. In a word, they’re sociopaths.
