It's typical in many European countries to stop the engine if you're behind the second car at a stop light. So this is a nice convenience to have.

You obviously don't have it in your car, otherwise you wouldn't say that. You want the engine to stop every time your car creeps ahead a few feet? You want all of that wear on your starter and battery? I always shut it off when I start the car. It's ridiculous for most people.

I do that myself, have for years. I don't need to be babysat by a Big Brother gadget.

I drive a 200 hp hybrid which already gets 49 mpg. I'm not concerned about fuel efficiency.
