Hmm, does it have a way of keeping the engine warm between stops and starts?
I'd imagine that provided the oil and block were kept up to temperature,
and you had an efficient way of storing energy to restart the engine it
should not be too bad.

The engine does not lose heat that quickly between stops and starts. To
confirm or refute this, turn off your engine, wait 3 minutes, and lay your
hand on the exhaust manifold or engine block.

When the engine temperature or cat temperature drops below thresholds the
engine fires back up. Some versions of the Prius reportedly have a "thermos"
to hold coolant warm between trips, but I have no direct knowledge.

Every 2004 through 2006 Prius sold in the US has that thermos. I don't
know about models sold in other countries.

I thought that would make me nervous, but it doesn't. Instead
it is rather nice to see that 0 and know you are not just
wasting gas when stopped (unless you have some auxiliary item
running).
