In California you can post a surety bond in lieu of insurance. I'm sure the same applies in other states with governance that is not captured by corporate interests.
It used to be 35k but it was increased in late 2024 (which is good because it hadn't increased since the 70s).

But to do that you really have to hate insurers or be uninsurable. Because realistically putting that 75k in a basic HISA will yield enough interests to pay for regular car insurance and you get to keep your 75k.
