and the engine will be off at stoplights.

Now theres a gas saving idea I haven't heard of yet.

That’s one of the ways Prius keeps good gas mileage in stop-and-go traffic. It can shut of the gas engine any time it’s not needed, and start it up seemlessly and without damage, because it can pre-spin the engine using the electric motor.

My engine is always off at lights (once the car is warmed up). So on my very short, stop-and-go drive from home to work (3 miles) I get over 45 mpg. An ordinary car would be lucky to be up to 15 mpg on that trip, especially if you catch the morning commuter train and all the red lights.
