Non-CO2 pollutants are side products of combustion. A cleaner combustion reduces their amount. Cleaner combustion occurs in healthy, well engineered engines with the help of clean catalytic converters. It means that new and expansive cars are less pollutant.
I still don’t understand why not USA / Canada, where cars are very common
