Anyone who parks in a disabled spot without a valid permit and whilst the permit holder is in the car should be shot on sight !
Just because someone gave them permission, i.e. the owners of the car park area, doesn't make it any less of an issue. ... there was still clear markings of it being strictly for permit holders only.
Most of the time I'll side with the Top Gear guys because the complaints are purely Political Correctness gone mad, but this isn't the case this time.
