Or wait until Covid ends and do border runs in Taiwan. It's how I spent 6+ months there or whatever it was. I was changing cities every month because the train system is pretty simple.
The hardest struggle is maybe 1 or 2 cities in Taiwan ban Uber and the local Taxi union ends up being anti-English or xenophobic. That may have since improved. If not you're probably not missing much if you purposely avoid those places.
Although in retrospect I don't see myself going back to Taiwan
