I had some dumbass in a roundabout come head on towards me because instead of them going right and going 270 deg around the roundabout like they should have, they took a left and wanted to only go 90 degrees the wrong way to take a "short cut" ... heading right for me. Half the people on the roads are too stupid to drive anymore.Yeah, I was in a similar situation a month or so ago (but I have no dashcam). Entered a roundabout and was intending to take the second exit straight across from me. A semi was coming down the first exit/entrance and blew into the roundabout at about 30mph without even looking. Had I not been watching him and anticipated that he was not slowing down and not looking, my wife would probably not be here anymore and possibly myself. He would have plowed straight into the passenger door of my convertible. Very scary!
