If you read the general internet it's all mobbed up guys stealing cars from law-abiding single mothers for no reason at all but then again if I believed the general public about parking violation enforcement here in germany I'd come to the conclusion they're the new jews.
So how bad is that whole privatized towing / enforcement thing, really? Is there an actual problem beyond "it's a private company" or is it mostly carbrain tears?
Every time I've had a car towed for a mechanical failure, the driver is extremely happy to be actually helping someone for a change.
