Especially since public transit is usually locally funded (at least in the US), in areas like this the tax base doesn't exist to be able to functionally fund public transit. We would need to completely rethink and re-organize how public transit is funded and rolled out for this to functionally work in remote areas.

Or, you know, we could continue lettings cars be a thing for remote populations kind of like how in some far northern territories people use snowmobiles to get around part of the year because there's simply too much snow to try to use another type of vehicle at all.

I think the latter, having specific types of transportation still be a thing in places where they're needed, makes a lot more sense, honestly.
