It would be not that inconvenient to not drive for local trips but very inconvenient for longer trips? Or vice versa depending on where you live
People are cooking over coal/wood around the world, that is far far far worse than everything I've read(and that doesnt include industrial pollution). (Although 2 stroke engines and their byproducts are cancer causing, so... that is still valid)
As for 2-storkes, I can't stand them, but they are still a necessary evil in many situations. I have gas and electric chainsaw. The electric doesn't compare in power and capability - but it is also my favorite, so I use it when I can. I love not smelling like 2-stroke exhaust, the electric always "starts" too. Then a larger tree dies or a dozen blow down at once and I have to break out the gas saw...
(Also, if it stays in the garage most of the time, it doesn't really harm anyone. I think that's only common for retired people, though?)
I don't know how to price it. Most people don't really think about it that way.
Our next vehicle will be a full electric but that will probably be another 3-5 years unless we opt to be a one ICE, one electric car family sooner.
Rain is nice, but that has very little to do with it.
The growth in moat of these countries is up so much they cant burn enough coal to keep from brown outs.
Outsourced pollution.
If you need data, just peak at a global air pollution map. Dive into the historical metrics.
