No Stupid Questions

This is one of those questions where you have to look to the past to really understand the possible future.

Rural America was built by railroads. You know why there's a town every 10-20 miles on a rough grid? It's because steam locomotives built during the 20th century would need to stop to refill on water every 10-20 miles. These old steam locomotives were slow usually only running up to 30-40mph. The train would need a spot to stop & refill with water so when the railroads didn't platte out towns to sell the land they just built through and increased the value of, towns would organically pop up near these stops anyways.

If we fast forward a little to the 1880s or so, electrification was going bonkers, and many electric companies would say "while we're building these power lines, what if we also ran electric trolley services too?" So the trolleys would advertise the versatility of this newfangled electricity thing while also providing a second revenue stream to electric companies. This is when electric interurban services really hit their peak. There were thousands of interurban lines across the US at this time, but many didn't survive out of the 20th century, and of those that did very few survived past the second world war, and of those, even fewer survived into being bought up by city transit agencies.

This pre-car period had most people either living in dense walkable cities or living on homesteads and walking/riding horses/carts multiple miles to go to the nearest town for the day. People didn't move around a lot during this time, and the world was much smaller and life much quieter. This is part of why circuses and fairs were so big is it was the most exciting thing happening all year.

The world has changed so much since the invention and proliferation of the automobile that it's really hard to imagine a car-lite world, but also there's aspects of modern society that simply can't exist without cars. I'm imagining a societal change pushed by something like legislation which doubles vehicle registration fees every year for a decade. Sure that $250 the first year will hurt a little, and the $500 the second will hurt a bit more, but you've got a good 3-5 years or so before it's really going to start hurting most families, and I'd imagine it would be the $4000 mark where most don't renew which is conveniently after 5 years of the registration fee doubling, and enough time for new bus services to be spun up and plenty of time for people to invest in bikes and manufacturing to adjust to the new demand patterns

The concept of road tripping becomes very different, and travel honestly gets more expensive. I was just looking at Amtrak tickets today chasing an idea of taking a couple day trip out of town during my kids spring break, and I'm immediately looking at $250 to go 200 miles, 5x the cost of just loading the family in the car and driving that distance

Without cars anyone living in rural areas is immediately stranded. Most of rural America has been rebuilt around cars because rural America was the first place cars were able to sell successfully (in fact car companies had to engage in conspiracies to force sales in cities once everyone who wanted a car had already bought one) there's many houses which are multiple miles from the nearest store of any kind, and many small towns lack any kind of grocery store. Many business and public schools in rural areas are located miles outside of any town and require people to drive or take the school bus just to get there. With about a century for rural America to rebuild into the car centric life that it is and most of the railroad tracks gone, it's pretty impossibls for rural America to de-car

Suburbs are similarly challenged to rural areas, but at least have the benefit of being close enough to their cities and hubs of commerce that biking and biking to/from public stops remains very viable. Exurbs where they aren't connected to the urban fabric but are entirely reliant on easy vehicle access to it are absolutely fucked though, and would probably spin up new Intercity bus services to compensate, but needing to transfer bus services to get to anything rapidly makes these already undesirable exurbs become far more undesirable

Small towns that never had the population growth to spawl are even better off. Many of these small towns are super walkable and bikable today with limited infrastructure changes that might be desired. Stroads built to serve big box stores or industries would be the only major challenge, but generally all that needs is a road diet and/or a dedicated parallel greenway

Shopping will definitely look different. For one thing single use plastic bags become completely nonviable since they carry so little per bag even compared to just paper bags, and it's difficult to carry more than about 3 plastic bags of groceries at once. We'd also definitely see a reversal from fewer larger stores which are further away back to many more smaller stores that are closer to people's homes. Parking lots will be quickly realized to be unneeded, likely to be torn up with new housing, stores and bus terminals built where those parking lots once stood.

The average road and street will also change dramatically. With people mostly walking, biking and taking public transit, suddenly the minimum acceptable street changes a lot, where right now it's relatively smooth pavement with relatively good drainage, in a world where people primarily walk, bike and take transit they will instead demand trees and narrower paved areas, bringing it down to human scale. A "narrow" 40 foot wide suburban street will rapidly become much too large and many will be rebuilt to be more pleasant for cyclists and pedestrians (I'm imagining 10-15 foot wide medians with trees, benches, water fointains and a nice greenway in the center, maintaining a pair of 10-12 foot wide lanes on either side for deliveries, emergency services and buses, or the inverse, with the road space narrowed significantly to 16-20 feet to allow for careful passing potentially with a parrelel greenway depending on traffic, again with trees, benches and water fountains)
