Trains, trams, anything. There are always going to areas, especially in the US, that 100% public transit is a pipe dream, but we can certainly try. In my mountain town I’ve floated the idea of a gondola that runs above the main boulevard the length of the valley (~7-8 miles) and people look at me like I have 3 heads. The majority of our town’s services are along said road, as well as hotels and tourist hotspots, so it makes sense to me.

Problem is you get the old-school types that think “public transit” = “you’re taking away my car!” and it always goes nowhere.
