From the same page, the minimum liability requirements are:
$15,000 for injury/death to one person.
$30,000 for injury/death to more than one person.
$5,000 for damage to property.
I have no idea if most people have way higher liability insurance than that. If they *don't*, then it seems like the bond "workaround" could be reasonable. I admit I'm not running out and doing it right now, but it is tempting. (I *think* I have the minimum required insurance on my cars, only one of which I actually drive regularly.)
If you rear-end someone's Tesla and total it, how comfortable are you paying $95K to replace his car out of your own pocket (or future wages)? Likewise, if he suffers any injury, you could be on the hook for lost wages, medical treatments (including expensive long-term physical therapy), etc. If he goes to the ER, you could exhaust your $15K medical liability coverage before the guy even checks out of the ER that day. And this doesn't even get into the pain and suffering and other indirect claims. Don't even count on support from your own insurance company, they may look at the claim and decide that it's easier to cut a $15K check than to pay a lawyer to try to reduce the damages.
You may think "Oh, well the other guy will almost certainly have medical insurance, that'll cover his injuries", but what few people seem to know is that insurance companies will sue the responsible party to reclaim what they paid out in claims from an accident.
Here's what Consumer Reports says about liability limits (who has no ulterior motive to get you to over-insure):
Your liability coverage pays for bodily injury and property damage that you cause in accidents. Don't get caught short by reducing your liability limits to the state minimums. Buying more coverage might seem like an odd way to save, but the benefit comes if you have a costly claim, which can put your personal assets at risk. Buy standard 100/300/100 coverage, which pays for bodily injury up to $100,000 per person and $300,000 per accident, and property damage up to $100,000. If you have a high net worth, boost bodily injury to $250,000 per person and $500,000 per accident.
If you're young and have no real assets, then a low-liability policy may be the way to go, if you have significant assets that you don't want to lose, think hard about your liability limits and what it really means if you're in an accident.
