That’s liability insurance, not comprehensive.
In the US you either have to have liability insurance or be very wealthy. Bill Gates has no need for insurance after all.
In the US, auto insurance policies are split into 3 buckets: collision, comprehensive and liability. Comprehensive kicks in for events which are “not collisions,” so tree falling on the car, theft, etc.
You are required to have liability and collision coverage in most states, but comprehensive is optional. People often drop it from their policies to save on the premium. I have tried doing that on one of our vehicles over the years but have barely realized any savings so I’ve ended up keeping it on the policy. Seems like others have fared better.
No state requires collision. If you've got a rust bucket, no reason to cover your own car.
Even if insurance went optional I'd still go fully comp, as the cost of a new car is not what I need if I'm already financially struggling due to injury
