Until you're poor you don't realize how cheaply you can keep a vehicle running, nor how many people are just driving around without insurance, license, and various other "necessities".
This is the secret underbelly to the car-centric design of the US. People drive illegally all the time. They drive over legal BAC limits, they drive without insurance, they drive unlicensed, they don't pay parking tickets, they drive looking down at their phones and not at the road.
When you're poor and you live in an area completely unserved by public transit and you lose your license because you can't afford to pay parking tickets, are you really going to stop driving and lose your job and become homeless?
We have statistics to show what unlicensed and uninsured driver crash and fatality rates are like and they're a lot higher than the rest of the cohort, but there's still a sizable part of the US population that does all of these things and still uses the same public road infrastructure as everyone else, often out of lack of alternatives.
And to get your car registered in most states, you usually only have to pass an emissions test, have a valid license, and have proof of insurance at the time that you register the car.
This means that 11 out of 12 months, you get to drive around without insurance.
Pretty much illegal everywhere in the US except for a few weird outliers. I think there’s one southern state that lets you have a bond instead of insurance?
