My personal favourite gripe - why the F*CK do we still need a tax disc? All the info is available to whoever needs it on the big ol database that also tells em we're insured and MOT'd...
Personally I keep the bike tax disc under the seat, had one nicked and another damaged by water. To the casual observer I have no disc... have never had an issue when stopped, in fact the last time i was stopped the nazi cuunt (who was only checking the speed of bikes and pulling each and every one, even though some cars were passing well over the limit!) was only bothered by the fact he thought my chain needed oiling even though i had degreased and relubed it 250yds earlier (I had just set off from home...) needless to say the bike cop stood behind him was ****ing himself when i told the **** this!
