https://www.epa.gov/sites/default/files/documents/CompilationofStateIdlingRegulations.pdfOnly states Stl. I assumed it would be correct. But this is regarding idling your car=ppollution, not about keeping your car from being stolen.
Well leaving your keys in the ignition while it's running is asking for your car to be stolen in a metro area lol. That is stupid and why anyone would leave their keys in their car anywhere is beyond me. We live in the middle of no where and I don't do that lol. That is a very different thing than it being illegal for smog/pollution reasons which is what tvguy was stating and what I was talking about. And yeah, the police have better things to do, but I have onstar so they can find it. And if not, well, thats what I have full coverage insurance for. If someone really wants your car, they'll get it regardless, so I guess I don't stress too much about that.
