A simple stop at a gas station or near a bank is living proof of how many people idle !!! It is unfair and disrespectful to the citizens and to the environment! The government should completely outlaw unnecessary idling . Idling of any form is not worth the amount of air contaminated .I have witnessed many idle only to keep their air conditioner running .I have also witnessed many cars around the city of Edmonton idling without any passengers -for well over 15 minutes in some cases!!! I If we even have a chance at saving our planet we should take those chances now ...and idling is selfish and careless ! It is absolutely unacceptable !
