The article suggests on average real-world emissions are 2-5x more than in the lab except for a 20x outlier. VW was 40 times more than in the lab. I don't thin

The article suggests on average real-world emissions are 2-5x more than in the lab except for a 20x outlier. VW was 40 times more than in the lab.
I don't think most of these cars are hiding anything, it's just an example of how easy it is to optimise for a fixed test.
