Minneapolis has a car idling law:
We caught about a dozen Minneapolis residents idling their cars past the legal limit this morning, and none of them knew they were breaking the law…15 minutes is all the time you have if you’re within Minneapolis city limits. In below-zero temperatures, drivers in Minneapolis can leave their car idling and unattended for up to 15 minutes. When the temperatures warm above zero, the idling limit is just three minutes.
“Maybe half an hour,” said Kissel, on how long she lets her car warm up. “But I wouldn’t know the difference. It’s the morning. You forget time!”
And yet they have no idle politician law.
It’s not a “green” thing; it’s about preventing auto theft – by making it illegal to leave a car in a condition where it can easily be stolen.
Honestly? I’d almost prefer the “green” law; at least it’d be stupid, rather than stupid and insulting.
