IdleAir

It was mostly a failed regulation. Some metro area started with this " Air pollution" Ozone stuff.. and nobody paid any attention to it. Some truck stops started implementing those idle air systems and not many people were using them.
One reason most people didn't use them was because the truck mfg's started making trucks "Idle Compliant" or whatever trucks. So they were legal to idle.
All the O/O's with those good trucks were parking outside the metro area's. There weren't abiding by the regs and the police weren't enforcing it out in the rural areas.

So, the idle air systems didn't last long for a few reasons.

 

It was started with a big grant from the feds. There were some companies that contracted with them to provide the service for their trucks. The system provided HVAC, and for additional charges, internet access and cable tv. I tried it but my biggest gripe was that if the truck that use my parking place before me had a driver that smoke some nasty cigars, or emitted some fouler odors, that same smell would come into my truck. I tried spraying Febreeze into the air intake but gave up and stopped using it.

That wasn't the first thing tried either. Any of you old hands remember Park'n'View?
