Very hard to police these. If they go on the road they get in the way of cars. Older people are not always very tolerant off hooting cars either.
I have met one or two nasty mobility drivers and being disabled myself I give them an earful. I got trapped against a shop wall by a reversing 'lady' driver who went off without a backward look. A good job the tin leg took the hit.
Avoid Skegness unless you wear shin pads. They are everywhere.
