I realize these cars are exceeding EPA requirements, but let's take a look at the overall picture here. It's a drop in the bucket when compared to anything else with a diesel engine on the road.. I can't imagine how much it would cost to completely redo the standards for driveclean for a few hundred thousand TDI's on our roads.
VW is going to recall the cars, flash them, they'll meet emissions, they'll probably get a few less MPGs, owners will be compensated and that will be the end of it.
