> Most companies decided to just pull diesel cars from the US market, and it turns out that all of the ones that stayed were tricking the tests in one way or another.

That's just not true. There were three options, stop selling diesels, implement a selective catalytic reduction system, cheat the test. All three were done.

What you are saying isn't accurate. A selective catalytic reduction system wasn't sufficient to pass the test without also cheating. Many of the affected VW cars did have selective catalytic reduction. Post lawsuit required fix these cars now use MASSIVE amounts of urea requiring constant refills, wear out the SCR components frequently on short intervals, and don't have nearly the performance they were designed to have. These companies were unable at the time to figure out how to get vehicles, even with SCR to have the performance and reliability buyers were expecting without also cheating on the tests. After the VW scandal, it was later found that BMW, Mercedes, Jaguar, Fiat Chrysler, Toyota, Nissan, and several other companies were all also cheating. I am not aware of a single diesel passenger vehicle sold in the ~2009-2016 time period in the USA that wasn't later found to be cheating on emissions tests.
