You could, but I thought you agreed with my suggestion that that was an anachronism? If you’re going to accept it is reasonable to ride on FPs, why some other arbitrary limit?
Just because we feel that something is an anachronism doesn’t mean that we can ignore the consequences of going against it.
I feel that the 70mph speed limit on motorways is an unjustified anachronism, because the car that I drive is capable of twice that speed and can stop a hell of a lot faster than the cars of fifty-odd years ago when the limit was introduced. But I choose to abide by what is expected of me because I am not prepared to accept the possible consequences of doing otherwise.
Again, I agree with you that not having a right to cycle on public footpaths is an anachronism. As I have stated, I do it myself albeit rarely. I am prepared to accept the possible consequeunces of doing so.
But the fact remains that just because we think that something is an anachronism, it doesn’t give us licence to act as we see fit if it inconveniences others.
