Caveat: For cars not equipped with automatic start/stop, the starter and possibly the battery might not be specced for it so it could cause additional wear. Cars with start/stop systems often assist the process with precise camshaft position measurements and the ability to squirt fuel pretty much right away so the starter doesn’t need to do as much work.
Also don’t do it with a cold engine - it’s better to get the oil up to temp faster, it’ll also reduce fuel consumption as the engine heats up.
