Actually I'm guilty of screaming profanities at people who drive those cars.
Not because they drive a prius as such; but because they need to get the f*** off my road because they clearly can't drive worth a s***.
I've never had a political discussion while filling up either. If there's someone else at the hi-flow diesel pump, the conversation usually goes something like :
"Mate"
"Mate"
"Gettin' expensive to put this stuff in aint it"
"Sure is. Glad this is a work vehicle".
"Well you have a good 'un then mate"
When I was driving a truck, I would see some of these shitbox cars, usually 20+ years old, usually "dogshit brown" in color, usually more rust than paint, usually driven by some pony-tailed, gray-haired prof looking type male, or some hairy. half-dressed (or Goth-dressed) feminist.
The cars had every available square inch of surface area covered with some moronic, left-wing nonsense on a bumper sticker. I'm not sure if they were there to hold the car together, or to advertise the intelligence (or lack of it) of the driver, but it would have been less noticeable if it was towing a flashing neon sign, powered by a portable generator, with BIG, BOLD letters saying: "WARNING: DUMBASS AHEAD!"
