Man Petitions to Ban Cars in UK

A UK citizen by the name of John McGlade has started an online petition to ban all private vehicles in the nation. His rationale?

This petition asks for the banning of the use of cars for private use, so taxis etc. would still be allowled [sic]. This will cut CO2 emmissions and reduce the effects of global warming. It will also create a better envirinment for all to live in with less noise, road deaths & fumes. Public transport should be massively improved to meet new demand created from this action.
So far, Mr. McGlade stands as the petition's only signatory. Maybe we should start our own campaign to mandate Mr. McGlade's use of a spell-checker. Or better yet, take up a collection to buy the poor clot a life. Who's in? [10 Downing Street]
