We need mixed mode integrated transport networks, trains and trams are great in many situations but they're not ideal everywhere. Current car culture is pretty terrible but self driving electric cars have huge efficiency advantages over other means of transport especially when fleet managed.

I've spent a lot of my life trying to rely on buses and they have a lot of downsides, one thing interesting is the bus Island and bus desert effect - buses end up pointing to corporate shopping areas where retail rents go up because there's more foot traffic, nice little independent shops get priced out and relocate to areas where no one can go because there's no buses... of course you'll say just have more buses but the logistics get really messy, you need everyone to be going to the same places or you're running empty buses. Trains are even harder to determine routes for because you either need it to be able to handle 100% of use cases or to also have a road network.

We absolutely need more rapid mass transit like trains, self drive fleet managed electric cars could make that possible even in rural areas
