I'll qualify my comment: "the very slowest people" are the majority _in the developed world_ where the median age is 35+ (Wikipedia). It's also where people are the most likely to use hoverboards.
In any case, you can dispute the numbers and it makes no difference. People are not born with wheels. We need space to walk about. By convention and by law, the pavement is not for vehicles.
Despite that, I'm prepared to share the pavement with people on wheels but it has to be absolutely clear that it's not my responsibility to avoid them. It's theirs. They are the ones choosing to put me at risk, they should take full responsibility for it. And watch where the bloody heck they go.
