I had to go read up on it and I was correct in my assumptions.
It'* a waste IMO.
The starter will prematurely fail because of the constant restarting...which will cause excessive battery draw and strain the charging system.
And doesn't the emission system go back into open loop every time the engine is started? Even though it may only be for a short time once the PCM realizes the engine is already up to temp? So when its in open loop, its actually burning more fuel.
So where does this save money?
And, its not safe. What'* going to happen when it fails to restart and you have to go into emergency mode? ie, avoid an accident and you need to move NOW.
