Motorcycles, especially Harleys, are not politically correct. They are loud, flashy, and often ridden for pure pleasure.
Prius drivers are helping to save the planet, so they feel compelled to strike out against anyone who doesn’t meet their standard of environmental awareness and responsibility.
The only two-wheeled vehicles that Prius drivers respect are pedal powered.
Doesn’t a Harley get better highway mpg than a Prius?
Plus, it uses very little toxic material that will later sit in a junkyard. Compare that to the huge battery and exotic materials that go into a Prius.
That’s why I refer to the car as a “Pious” instead.
