Who are these "Western people" you refer to? Here in my part of Western Europe (and many others) gas scooters are everywhere and have been for decades...
Not to mention there are places with much more bicycles than the US (even despite the weather, like in the Netherlands).
I'm not sure how electric scooters are inferior, the solve a lot of pain points of gas scooters. They can have much better acceleration and start much more reliably. Range isn't a big issue because you wouldn't want to take a trip longer than an hour or so with a scooter anyways.
And the user experience is great .. open the app, find a scooter, walk to it (Viennese people walk.), rent it with the App, hop on and ride away .. park it where you want, finish the rental, voila .. easy, fun, smart access to an efficient transportation system.
People want these services. Its happening.
They are everywhere here in Malta and it is reducing traffic congestion very noticeably.
