Because I don't know how they can police non registered ones. I can imagine plenty of non registered ones being about.
Yes but do you drive your bed down the road among the heavy trucks who can't see you ? or the speeding car drivers who don't give a shit or are off their head ? Do marathon runners run around the M25 ? No, they have a cordoned off road. There's mamby pamby attitude and there's common sense. If you had a son/daughter who died because they had an accident on a scooter and weren't wearing a helmet, you would maybe change your opinion. No ?
Dou Doubt it you’d need both hands on the handle bars otherwise they’ll fall over And doubt they’d cope with a pillion
If you hold your bike handlebars just by the headstock rather than the grips you’ll see how difficult it is to steer and one handed nigh on impossible So if a little scrote tries mugging you, a gentle pull or push should have them face planting the pavement and nicely softened up for your chosen form of justice
