for my 100th post i figured id ask a dumb question. dumb but i have not seen the answer anywhere so i will ask. considering the pzev's great reductions in pollution and what not, is this car safe to run inside a closed area like a garage or enclosed building? or would you still have to fear the carbon monoxide? i assume the car puts out alot less than normal and it would be safer to run inside for longer, but i believe it would still be ill-advised. anyone know for sure??
