Side note here on how ludicrous it is that you can substitute a $35,000 bond for a real insurance policy, given the likelihood that any driver is going to cause losses far in excess of $35,000.
Minimum insurance in California only covers the same $35,000. $15,000 for injuries to one person, $30,000 for injuries to multiple people, and $5,000 for property damage.
It's completely insufficient, but it's not nothing. A reasonable person would carry much more insurance.
The 35k bond doesn’t preclude getting sued for an unbounded amount. Presumably the idea is that a 35k bond demonstrates you have more available in case of a judgment.
That said, that seems like a risky idea in a world full of LLCs, trusts, etc.
