Gas-powered cars are indeed much cleaner, they are very popular in Armenia because of favorable pricing compared to petrol. And while air in cities here may not be very clean, it's generally not because of cars: people burn trash in winter and there are a lot of dust in the summer.

Thankfully many new cars are Chinese EVs and most people are installing solar panels, and it doesn't seem to be environmentally driven at all, just economics.

LPG cars are also very popular in Poland, because of fuel prices. Not sure about new cars, but if you buy a used car that hasn't somehow yet been converted to burn LPG, the conversion is pretty much the first thing you do.
