The phenomenon you're describing gives rise to the last mile transport problem, which is notoriously hard to solve. You either want something which is compact enough to fit on existing transit systems or exists in a sufficient quantity at transit nodes to augment human mobility and smooth out the gradients between transit nodes. I'm hoping that as battery and motor technology advance we'll be able to miniaturize personal transit technology enough to make such devices ubiquitous.
