While I admit to using my electric bike on some of the pavements here, I always stop and dismount when I see a pedestrian, say 'Hi' then toddle off.
Kent County Council are hopeless at mending road potholes around drains, and some along the Rye Road are over an inch deep, so I have to steer round them, which shakes up the Growster-things more than somewhat... The pavements are much safer, but I don't usually ride on them, because if someone pops out of a drive, I'd be at fault.
When I go up to Highgate here, (the main street), I usually go around the lanes, but because these lanes are a designated rat-run for everyone, I'm still in some sort of 'danger', but being or sterner stuff, they get a wave when considerate, and a Harvey Smith if not!
But these scooters are difficult to assess. They shouldn't be on pavements, but who is there to tell them not too? It used to be the local copper (we had three once), but not any more!
I reckon a few shoves in the right direction could be quite a nce answer, but then I'd be arrested!
