There's clear evidence that many cities throughout Europe have too high air pollution, and that it kills close to what smoking does. Cities have been ordered by the EU to clean up by the end of the year, or face harsh fines. Over 80,000 people die in the UK per year (smoking kills 100,000). Mostly from diesel engine pollution.
Now try to think how many people it kills in the rest of Europe, the USA and the world?
Cars (and buses) stink, are noisy, and worse -- they kill on a massive scale. There is alternative tech available for order now that doesn't kill as much, and provides better service.
Demand that the killing machines are replaced, and the makers, and the users are brought to justice if they don't!
