> I would ride public transportation

Even simple things like this would be difficult. For starters, ticketing tends to be powered by 5G on buses and over physical networks for permanent fare gates like at a railway station.

Bus arrivals screens and boards at stations are also fed by the network.

I guess if we take a generous interpretation of the OP's question though, those would still be able to function assuming they work over a private network instead of the internet.
