You can just turn up in SYorks so long as you behave like a car with regard to queuing and parking BUT, there are cases of pedestrians walking everywhere across the entrances and cyclists riding in by the exit because “they are not a car”. A site in the south had pedestrians walking in from their cars because they didn’t want to queue and one was run over by a car. Hence some form of tightening of restrictions. If this saves my council paying out for claims I’m all in favour.
