Your comment can be summed up as "Just have money." If you can't afford health insurance, you can't make sure you're covered. The only option is to not have it and to go to the ER whenever there are problems.
Cities find ways of ticketing you. They make $20M/yr from parking violations. If that revenue drops, they'll change the rules until it goes up again. https://www.youtube.com/watch?v=0UjpmT5noto
For example, there are tow traps that don't look anything like tow zones. I've seen at least five cars fall into it, myself included. The city won't change it, and you can't fight it.
Another example: Street cleaning. It's a euphemism for "Move your car or we'll ticket you." No one shows up to clean the streets, ever, but they're there at 8AM to write you a ticket. When you're forced to park on the street, you can't get away from this. And the notifications for street cleaning often appear between midnight at 8AM, meaning you can end up late to work or with a $150 ticket if you don't pay rapt attention every day.
