enlightened us thusly:

And what do you think happens to all those removed catalytic convertors that
have all sorts of nasties in them when they get removed? Ah, good old
landfill!!!! LPG is currently the only commercially viable alternative fuel
that IS cleaner than petrol or disiesel, hybrids still burn petrol and store
all sorts of nasties in the cat for the future, hydrogen production is
probably more environmentally unfriendly than running on petrol in the first
place, and di-lithium crystal matter/anti-matter warp drive engines are a
long way off! Now, howsabout a nuclear powered turbine
engine/generator/traction motor set-up?

wot, like the one in "the Big Bus"?
