Whether or not the engine is turned off,

The adoption of automatic engine shut down and almost instantaneous
restart that manufacturers have develpoed to reduce emissions and fuel
consumption could fudge using that, as will hybrids whose IC engine
has shutdown as the batteries are charged enough.

Yup, lots of mini cabs are now Toyota Prius's and the like, whose engines
nearly always shut down before the car stops, and don't start again till
some distance after it moves off. That's a lot better than a rank of
smelly, rattly black cabs.
