Well, you could put in 'Bikes are a disgrace to the city'...or 'walking is...'. Same effect.
I don't think jumped up kids toys ridden by exercise-averse people who have the need for speed and crave convenience yet are afraid of roads so swarm all over pavements is a terribly good idea. Neither is it a great idea to permit 30-40 mph souped up top range escooters onto cyclepaths intended for non-motorised traffic just because some people can't be bothered to pedal. It's leading to the motorisation of cyclepaths by the convenience addicted who avoid effort. Okay, in the Netherlands they allow 'bromfiets' - 50cc mopeds - on cyclepaths but to me that's just daft. Amsterdam banned them from cycle lanes a few years ago for obvious reasons. If we allow speedy escooters on cyclepaths, how long before the moped fraternity start arguing the case to ride on them at the same speed?.
Back in the 90's there was
one bloke who rode around Bristol on a petrol 'go ped'...look what's happening now, electric 'go peds' all over the shop. Dumb idea then, dumb now IMHO.
