Not trying to be a smartass (or dumbass) depending on how you look at it...

But, how does one regulate this???? Someone follows with a stopwatch or the car automatically would cut off??????

Can't wait. We have some of the worst air quality in the nation. Hopefully they'll pass the no-diesel-idle rule soon too, which would allow diesels to idle only 15mins/hour, or something like that...
