Thing is, if we’re conflating hate for other drivers with hate for other cars, the absolute worst thing on the road is buses because bus drivers absolutely never obey certain traffic laws like “drive in one lane at a time” or “no changing lanes without signalling”, and when they park by the side of the road, it’s way worse than when a mere car does it.
Seriously, bus drivers are the exact opposite of 18-wheeler drivers. They’re the bullies of the street.
