Yes it actually works when it's in Park position too Belker ,I forgot.But when these vehicles were first built in 1998 they were miles ahead of diesels in terms of emmisons so they weren't deemed to be a big poluter.There was a time when half of Hollywood were driving them to show their planet saving bolloxollgy side when they weren't driving their Hummers and Lambos.
I'm sure in time they'll test them eventually but petrol engines aren't big fails at the emmisons tests AFAIK.
They don't use very much juice so they can't really pollute that much.I think Toyota had some marketing shite on the back of a bus saying one diesel engined car gives out more Nox gas than 20 hybrids.Dunno how true it was.
