This is a wee bit scary. Those photos look like stills from a low budget slasher movie.
I agree about “Hesitant Turners” and not just at lights. What I hate the most is when I’m driving through the nearby small town, where the speed limit is 35 MPH, and the person in front of me slows down to 10 MPH, then 5, long before they get to the parking lot they’re going to turn into, taking an agonizingly long time creeping up on it. Sometimes I wish I could look really scary when people do that.
