I'd really like to see an officially implemented option to decide whether your car should spawn with a running (status quo) or stopped engine. Since you've already put in the effort to implement realistic starting sounds and letting us choose between pre-heated and cold engines, this would be a nice addition towards realism! I'm sure someone has brought up this idea before me, but I probably didn't use the right keywords to find it ^^ Or maybe it's just me who's interested in a feature like that...
