Have a look at the attached for a couple of cars parked on the pavement first thing this morning. It was my understanding that you're not allowed to drive across any pavement where the kerb has not been dropped - the question here is about enforcement.
Interestingly enough, it wasn't long ago that BarCar was on here saying that the council allow parking on the pavement on his road, but refused to drop the kerb. So it isn't quite as simple as that.
That's not to say those cars are right - they're probably not.
