Electric Scooters

I sell electric unicycles and have been using them in London since 2014 with no issues. The law (from the Victorian era!) states they can’t be used on pavements, and the highway law prohibits them from being used on roads with other motorists. But the police don’t really care - they often just ask with curiosity and let me be, but I guess that’s different if I was an inconsiderate user/rider. I’d imagine the same applies to e-scooters and e skateboards (which I was going to sell as well but I think my eucs are way cooler)
