That's what he said.

Yep, you're right, I'm wrong. Didn't read it right the first time. :-(

Wrong. A rear-end collision will directly impart kinetic energy to a
Prius (which could be recaptured by braking). As would a meteor strike
or a nearby car bomb detonation, an earthquake or any number of other
usually unplanned events.
You could even charge the traction battery by having someone push the
car while gently applying the brake with the HSD engaged.
Of course I agree that all the talk about wind and hills is simply due
to a widespread misunderstanding of basic physics - unless the hill
grows underneath the car as it sits still or the wind is hurricane
force and directly from the rear. Other than that wind merely
increases or decreases the aerodynamic drag (as does the design of any
vehicle).

And the hand of God could come down from the sky and push it along, too.
What other ridiculous examples could you come up with?
