I think the seeds of that good idea became the much more compact electric scooter (Bird and friends), and for those willing to climb more of a learning curve, eskate and onewheel. The critical thing for all of those, though, is that they can work as last mile devices because you can carry them indoors, onto buses/trains, etc. A segway is strictly worse than a bike in that regard because you still have to park it outside somewhere, but it's an awkward shape that doesn't fit into the usual facilities for doing so (and obviously it wasn't supposed to get wet, either).
