The difference is that you rode bikes for sport. We're doing it for a living.
Many of us are bikers, too, btw. I also take part in Classic Trials. The last time I rode one of mine off a surfaced road, (legally, carefully, quite slowly and well away from habitation) we were accosted by a woman who was almost violent in her protest. We had stopped to let her go past. She insisted in taking our registration numbers and told me she was going to report me to the police for riding there. I pointed out my friend on his bike, on her other side. He merely said: "Why not tell me, then - I AM a policeman". She became even more agitated so we rode on. Never heard another thing.
As I write this, another light aircraft has flown over my house at less than 500 feet on it's way to the airfield. I won't be complaining.
