I have been passed by a young male riding an electric stand up scooter. I was doing 40 on a dual carriageway, and he flew between the 2 lanes and zoomed off so must have been doing at least 55/60. No protetcive gear on either, just jeans and a tee.
I would put good money on this not being at all what @larmen is talking about .. I'd say he is using a perfectly legal one
I've never seen the illegal ones to above 30 but then they can be modified as with any tech.
