I believe I read years ago that new Japanese cars (maybe for the Tokyo
market only) were being equipped with devices which would automatically
shut of the engine when the car had been stopped for a few seconds.
The device would also restart the engine the instant the driver hit
the gas. I assume it could only have been done for air pollution reasons.

Sorry, no source on this.
