Modern cars actually clean up the air they burn in terms of

Not quite yet - some new cars do manage this, in a dense city environment
their emissions *are* cleaner than the ambient air. But only when brand new.
And only in polluted air in the first place.

It's a good start though.

So, what we want in heavily polluted cities is more (new) cars! ;-)

And apart from the new fuel cell buses all the diesel ones need to
stay out of the city centre (doh .. PT ..)?

Is it Japan when any vehicle over 3 years old / 60k is 'scrapped'
(sold to us more like)?

All the best ..
