So Mr Larrington's twin has: 1. RLJ, 2. Share the road, 3. No riding two abreast, 4. Ride in the gutter, 5. Compulsory helmets (please don't consign this to the helmet section!, 6. Compulsory Hi Viz, 7. No lollipops
I propose 8. Compulsory insurance, 9. Road tax for cycles & 10. Compulsory bells/spoke reflectors/front reflectors
Banning cycles not a good idea because our twin would have to start on say pedestrians, which is a harder target.
I don't think banning cargo bikes, tandems, triplets, recumbents, tricycles, electrically assisted pedal cycles; flashy lights, 20 million lumen non-dipped headlamps; overtaking motor vehicles & etc would occur to Mr Evil Twin but perhaps others may disagree...
