I've been into London twice in the last year and each time I have seen bikes parked on the pavement with the license plate covered The first time I was in a bar and across the street was a bike parked on the pavement under a "no motorcycles" sign with a black plastic bag tapped over the plate, a traffic warden was milling around the bike but didn't appear to ticket it. The second time I was in Hampstead and a bike was parked on the pavement with a piece of white paper folded over the plate, a traffic warden seamed to be debating whether to lift up the paper or not.. Is there some loophole in the law that allows you to cover your plate and not get a ticket? Is it that the warden can't touch the bike...seams unlikely if they can put the ticket on the dash? Any ideas? Regards Gaz
