While everyone whinges about clamping, and some of them take the mickey I do think to ban it is unfair on landowners.
As part of my job I manage various buildings. A few years ago one of these was close to the centre of Doncaster, with a car park at the rear that could not practically be secured.
The building was let to multi-tenants. Biggest part of my job was dealing with car parking complaints, including the public using the car park, people deliberately parking outside bays to make it easier to get in and out (instead of reversing in) and making other spaces very hard to access and parking in each others space. A great ball of poo basically.
After various letters etc which were ignored we went to he nuclear option. Clampers. Public problem stopped. The people who would park outside their bays, did not. The only problem we had was when a firm of solicitors sent staff without passes who got clamped - and then lied.
I personally think the problem is the system and it should be fixed, not outlawed,
After all why should the government get to use clamps, and not private land-owners?
