I hear you. I imagine getting old living in a "american suburb" and no longer being able to get around independently. Especially once I loose the ability to safely operate a vehicle, for my own safety and everyone's around me.
Coffee shops, butchers and pharmacies should always be within a quick 10min walk IMO in any suburb, or a short bike ride or tram away.
Most people now a day don't drive, not because they can't, but because most choose not to. Especially if they have access to viable and accessible alternatives like trains, subways, trams, buses or a bike.
I do agree with your statement "feeling trapped" and not able to go anywhere.
This TBH comes down to how our cities and towns are designed, somehow only assuming everyone no matter their age or background or income can drive. Hopefully this changes in the future someday to allow people to get around more enjoyably, independently, comfortably.
Now that being said driving schools exist. You can do a in class session for the written test, and then you can get a driving instructor that takes you around for 5 hours or more if you want to practice things like parking, parallel parking, left and right turns. You can also schedule longer sessions and multiple sessions as needed.
Basically any one of the various NotJustBikes videos highlighting shitty half-assed infrastructure designs in north American cities throughout the US and Canada.
People rarely complain about infrastructure to thier local governments so nothing rarely improves
I was imagining "into the future" though, where everyone has a device that meshes with like devices, creating a internet of connect devices to transport data over large distances. All decentralized, if one node goes down traffic routes a different way in the mesh.
Think Cellphone Towers for examples, but the idea is everyone would have their own device at home (or on them) that instead creates the mesh and simultaneously access the mesh.
Same, decentralized mesh networks would be the equivalent of a "federated internet". No one person owning the infrastructure.
If this were to become mainstream the mesh would become the "Internet", with enough nodes, pcs and servers.
And in the meantime where one mesh does not "connect" to another, traffic could be routed through the "old internet" by one or more exit nodes connected to the "old internet".
People in my neighborhood constantly cut speed cameras down every other week, do with this as you will.
