I'm surprised and disappointed that you give any weight to these kind of reports, Bruce. They are always funded by environmental groups with their own motives.
But more importantly, their methods and conclusions are highly debatable. Pollution certainly does NOT cost 9500 lives in London a year. That is sensationalist nonsense where they extrapolate extended life expectancy and improved health from less pollution... BUT that is a fantasist world. If you removed traffic then business would stop and we would be plunged into rat-eating chaos. I don't think health and life expectancy would improve under those circumstances. If you wanted you could just as easily design a study that showed the commerce and wealth that is generated from motor vehicle activity in cities raises standards of living and therefore increases life expectancy.
