I feel fortunate to make enough money to easily afford the rent, but it's insane that in most places you need a high paying job to escape needing a car. Refugee and low-income housing here is clustered around major streets like six-lane one-way transport corridors. Unless they work downtown or close to a stop on one of the few bus lines that run frequently and reliably, they need cars. Usually the cheapest they can afford, which likely means they need to spend money they don't have to get them passing emissions tests at registration time, deal with breakdowns, high insurance premiums, etc.
It doesn't help that most of the planned transit improvements seemingly are focused on greenification of buses rather than just getting more buses on the road to expand routes, make lines frequent enough to use for commuting, etc.
My city did pass some new zoning codes which heavily cut back on parking requirements, I'm excited to see how that (slowly) pans out. I expect more high-capacity parking structures to go up, fewer surface lots. People might need to walk further or explore other last-mile options, I have hope that will turn people's eyes towards non-vehicle transportation improvements.
Take something as far back as New York in the 60s depicted in _Mad Men_: Don Draper commutes by train. He lives a little away from the station, but that’s hardly something a well-timed local bus couldn’t easily bridge.
Many people still do today. It’s the same thing in most capitals where I’ve lived, and those big enough to be featured in movies. Suburbanites commute to London, Paris, Copenhagen, Stockholm, Chicago, Tokyo, Moscow, Delhi, Peking, Shanghai, and every large China city by local train. I know places where people don’t, but I can’t think of a single place where that’s not a nightmare.
Saying something like "New York" immediately invalidates the rest of your comment as New York (City) is one of the few areas with meaningful public transit.
We worship cars here. Cars are like Freedom Jesus. If you do anything to mess with cars you are a filthy communist who should die according to the general public.
Every suburb I have lived in has been walkable for the main items (grocery, bar, getting to public transit). If you want to live in the suburbs and walk you have to make that your priority but it is very doable.
