Cyclists - obviously!
There is a lot of competition - but there's no real doubt about the winners.
Cycling is just a minority hobby pursued by boring monomaniacs; yet my home city has spent hundreds of millions of pounds, and subtracted hundreds of millions of man-hours from the lives of its resident, to accommodate the whims of this tiny cadre of selfish, over-indulged pin-heads.
Cyclists are also arch-enemies of the mass majority of sensible, decent, real people: salt of the earth: the pedestrians.
