the tricky question: did anybody figure out how to do a clean enough diesel engine without cheating?
i think its funny that European countries were pushing Diesel engines just because they emit less CO2, disregarding the NOx problem.

Yes. It is just more expensive in terms of maintenance because the urea-based cleaning liquid ("AdBlue") needs to be refilled by the dealer a lot more often if the exhaust scrubbing doesn't cheat and disable it half the time.
If you are interested in the details of the topic, I can recommend this CCC conference talk from last month:
European nations aren't "western"?
Actually European nations is what it originally meant. Western European.
https://en.wikipedia.org/wiki/Western_world
The term originally had a literal geographic meaning. It contrasted Europe with the cultures and civilizations of the Middle East and North Africa, Sub-Saharan Africa, South Asia, Southeast Asia, and the remote Far East which early-modern Europeans saw as the East. In the contemporary cultural meaning, the phrase Western world includes Europe, as well as many countries of European colonial origin with substantial European ancestral populations in the Americas and Oceania.
Europe was the West, then you have the Middle East, then the Far East (China, Japan). That was the whole world to them pretty much. When the Americas were discovered they were known as the New World, and eventually became known as the West as well (Due to the fact that most of our culture comes from Europe, eg. Western Culture).
I suspect Rome (or some other city in Italy) is the centre of these terms, but I haven't looked for evidence of that.
