In case you weren’t cold and angry enough this morning, this is your friendly reminder that it is illegal to start your car to warm it up and then leave it running unattended. This, of course, could throw a massive wrench in your morning plans. The good news is that there’s a loophole in the law, that being the use of remote starts. A vehicle turned on using a remote starter system is not classified an “unattended motor vehicle,” the law says.

While remote starts are okay, Chicago police has advised against it due to the possibility of theft.

Stay warm, Chicagoland.
