There are some good thoughts and questions here. I'll check out all of the cities listed & the New Urbanism / DPZ communities. Here are the answers to a few of the questions / comments that came up:
I'm not surprised you're having difficulty finding an affordable community without cars.
I should have specified that my definition of affordable is pretty flexible. We own our house in the San Francisco Bay Area and could move most other places in the world and pay far less than what it costs to live here.
Is a place like New York City out because it has car-lined streets?
New York City is out of the question because even though most people are able to walk, bike and take transit, somehow the car has still overtaken the city. Cars are parked everywhere & packed into the streets, so it's super loud and many many pedestrians and cyclists are injured and killed every year by cars. Despite that, the city continues to prioritize private car travel and parking over things like bus rapid transit lanes, protected bike lanes, improved pedestrian crossings, etc. It's a fight for each project because parking or a lane of private car traffic is going to get eliminated.
Are we just talking where walking, biking, and transit are the dominant form a transportation, or do you mean places that are actually car-free? I'd say totally car-free is not that common anywhere in the world.
Also, are you talking about staying in the US, or looking at the world as a whole? Also are we talking just big cities or smaller cities and small towns?
I'm looking for places where walking, biking & transit are the dominant forms of transportation. Meaning that they are actually prioritized over private car traffic. Places where the streets aren't packed with loud cars & where pedestrians and cyclists aren't frequently getting run over.
The US is preferred (but I feel like unrealistic), so we're willing to consider anywhere in the world - big or smaller cities or small towns.
Where we live now, a car is not needed. Our current house has a bike score of 99, walk score of 82, and transit score of 62. We can easily bike, walk or take transit everywhere locally including to work, kids' schools, groceries, hardware stores, festivals, other entertainment, etc. On paper it's great, but in reality despite this fantastic accessibility to nearly everything, most people still use their cars for almost everything. So there's still traffic in the City Center and in shopping areas that would be much more pleasant without cars circling for parking.
The motivation for my question is that I have been hit by a car as have many others that I've spoken to. Many pedestrians and cyclists are seriously injured or killed every year in my city and there's still a huge amount of pushback when the city tries to remove even one parking spot for a bulbout or more visible crosswalk or a protected bike lane. And I'm not even getting into the environmental, noise or overall quality of life impacts. I feel like this attitude that "car is king" is the norm in the US and was wondering if there's a place where we can go where the cars / driving is truly minimal and where people are prioritized.
