The European automobile industry is proud to announce that we don't need to reduce emissions through a modal shift away from dependence on all having our own cars.
We simply have to spend £500bn resurfacing all of Europe's major roads with lower rolling resistance surfaces. And by "we" they mean "you", not "they". I'm sure car addicts will happily have this level of subsidy tacked on to their "road tax" on a per machina basis.
