This is going to sound like an extremely dumb question, but since I do dumb questions so well, I might as well go for it.

I took my HCH2 to the car wash today. As it gets pulled through, the engine is always idling and my average MPG just plummets. Is it a big deal to shut the car off while in the wash and restart it when I exit?

See? Dumb, right?

This car could really use a forced EV mode like the well known Prius mod.
