It means you are dependent on cars for one, which also means insurance companies, gas,car payment, etc... I am actively trying to ditch cars in a car city because of this. You wastr so much space for parking lots too. You interact with a lot less people because you are always at some destination with the journey barring you from interacting with the people of the city. Physical fitness and health is also affected.

It is ridiculous. In order to have food and shelter you need to be dependent on not just a landlord and grocery store but also insurance companies, car dealers, oil and gas companies, DMV/DPS,mechanics,etc... and infractions against driving law can leave you unable to work, get food, go to the doctor (outside of ER),etc... a traditional city does not require a regulated license for teansporation and you don't spend almost as much as rent on transportation. Especially for low-income people, liquidity is important, it is the reason behind why it is expensive to be poor. Think if all the tragic social cost that can be avoided if people can instead spend money on their other needs instead of cars.

I read somewhere how car makers bribed and played dirty to prevent things like rail cars from being adopted by cities. To me it relfects on how much corporate-run the city is.
