Also, cars don't make that big of an impact on emissions compared to agriculture, trucking, airplanes and electricity generation. Even if we ALL stopped driving our cars and walked, we're still producing 80% as much of the greenhouse gases than if we were driving.
While that may be the case statistically, in inner urban areas cars are the most concentrated source for air pollution/ emissions. Most of the other sources reach us over a longer distance and diluted in most cases. Cars turn cities into nightmares.
Many Asian cities, like Phnom Penh, can barely cope in the busy inner areas and with growing affluence and not much room to move, it won't get better, it'll get worse.
To be fair, if pollution controls are instituted (which many places they aren't), then it's not so bad. I've lived in a lot of tightly regulated cities, but the place I've replaced the most cabin filters in my vehicles in is here in Cambodia (I didn't have a car in Vietnam though, so that would have made it worse for sure). Most of the pollution honestly in Phnom Penh comes from the motos and lorries, not the cars (although I know you weren't referring to PP specifically in your example). Cars here are the cleanest running vehicles on the road while a moto can scarily put out 90 times more CO and all sorts of other nasty stuff with it's complete lack of emission controls. It's mind boggling, but if you put a little moto on the sniffer and then a massive Land Cruiser, the one to fail the cleanliness test wouldn't be the 380 hp V8, but the 5 hp little bike.
