When we say the gasoline engine shuts off when we stop we're actually doing
the uninformed a disservice. Traveling at 35 mph on level ground, my Prius
will coast for at least 500 ft without the engine running or the electric
motor providing forward momentum. If I let up on the accelerator too
prematurely to make it to my stop then I'll press down lightly so only the
electric motor brings me there.
