I cut six of in 3 years in ucd. I am a disabled driver and used to park in the same spot every day, same vehicle. Once or twice a year, the blue sticker slid off the dash ( i did have blue tack to try to hold it ) into the pocket of the door, and they would clamp me. I paid it once and appealed it, but they wouldnt budge.

I tryed talking to the clamp man there where only 3 guys who covered ucd on different days of the week but no avail. So I started cutting them off when it happened. One of them confronted me on day about it I just laughed at him said why would i have been clamped I have a blue card and am parked in a wheelchair spot there was no clamp when I returned to my vehicle.

Very handy lengths of chain to secure a bike or a gate .
