I have a question, page-13

Under powered scooters ? Do you mean slow ?

Ideally scooters and cars need to separated. And from pedestrians ideally. Then the speeds should be less of an issue.

Yep. Kids are good on scooters. It makes sense that they should be able to do that well into adulthood and continue the trend. I've got a mate in his fifties that rides a scooter in a skate park like a Boss. Much to the embarrassment of his kids. He is a very good skateboarder of course.
