I dunno, I feel like it's mostly just people being people. We have a truck and a sporty little hatchback and people are just as apt to drive like assholes around both cars, despite my husband and I both also being the "drive just enough above the speed limit that we probably won't get a ticket" drivers, and otherwise adhering almost exactly to road laws the way only mildly obsessive neurodivergents can. I think people either just don't know road laws or don't care about them and get pissed when other people do and "impede" their oh-so-important trip.
