Once you have the necessary portable emissions testing equipment, how much work is it to test a vehicle?

I've been wondering why the researchers at WVU who found the VW cheating have not gone on to test a larger set of vehicles to see who else is cheating.

Do we know the researchers haven't tested other vehicles? If VW were cheating to a greater degree than other manufacturers, that might explain why they were the first to be caught.

Yes, they weren't doing this on their own initiative, they had a contract to test 4 specific vehicles of which 3 were VW TDIs, I think. They didn't initially think they'd found cheating, and it took a year or two for CARB to get interested and things to develop.

You'd think someone would fund broader testing...
