This is encouraging:
An Ottawa committee will consider Tuesday a bylaw that would ban idling for longer than three minutes except under special circumstances.
…the bylaw would include exceptions for drivers stuck in traffic, as well as those trying to keep warm on days colder than 5 C or trying to keep cool by operating their vehicle’s air conditioner on days hotter than 27 C.
I think drive-thrus such as those at Tim Hortons (*gasp*) should be banned, too. It’s amusing and sad to see cars idling in line for minutes waiting for a a buck-fifty coffee. Park and walk in!
