Waaaay too many moving parts if you ask me.

I have an alternative idea: Electric monowheels(or kick scooters):

-Not fixed-route.

-Barely any maintenance.

-Even the non-exploding ones cost as much as (subsidized) public transport over their lifetime.

-Same speed as this moving sidewalk and bicycles - could potentially share the bike lanes with the latter.

Two major disadvantages though are weight and usability in bad weather. I guess nothing beats cars when it comes to comfort of traveling.

Why is being fixed-route a bad thing? When you already have city-scale capacity-planning data saying that 100k people make a particular trip on a particular route daily, building fixed infrastructure to accommodate that route usually ends up with a much lower TCO than the equivalent mobile infrastructure. A subway train costs less in maintenance, fuel, and road-congestion than the equivalent number of busses, to serve the same load on the same route. Mobile infrastructure only gains an advantage where the load on a route isn't enough to pay back the capital costs of fixed infrastructure (e.g. busses out to a depopulated exurb.)

Buses and trams and subways are fixed route. Also, they are dependable. Sometimes foolproof and simple is better than infinitely flexible.

It's called a Segway.
