He forgets the part where because of emissions requirements the C15 can't be driven in that scourge the people the author defends call "low emissions zones".
If you want to live in polluted areas there are plenty of places available on Earth for that, I believe most people would rather not. Low emissions zones are mostly in very densely populated areas where the impact of pollution is higher, not sure why you consider that a scourge.
Could you expand on why?
Good so the car won't be killing people due to high noxious emissions.
