It&#x27;s not practical to design everything in the world with the very slowest people in mind. The efficiency losses would be huge. Imagine if every pedestrian crossing light went for five minutes. Vehicular traffic would grind to a standstill.<p>That said, I see no reason why the people riding these things couldn&#x27;t just move around other people. I rarely have problems with people on bicycles, because we can mutually avoid each other.
