As has been suggested, to make a case for infringing an 'Except for Access' zone you really need to be observed throughout its length, which is virtually impossible unless you're followed by an enforcement vehicle. So I don't see how they're actually going to enforce this restriction, bearing in mind they have to prove you didn't 'Access' anywhere, which the 'timing' cameras won't do, rather than you having to prove you did.
