Not many other countries intentionally bankrupt accident victims the way the US does.
I don't live in the US, and I agree. But, if you're found liable for an accident you will tend to pay a lot of money in any country; the accident victims likely have life or accident insurance and their insurance company will want to get reimbursed.
So good, comprehensive accident insurance is a very good idea no matter where you live. Usually we have that as part of our home insurance or other thing like that, and if you own a car you have mandatory insurance for that.
But in a case like this you may well be completely uncovered. The vehicle insurance is likely not valid for commercial traffic, and your home insurance may well not be valid either. As I said, I would never, ever get into a car like this without first being absolutely sure that the liability situation is crystal clear.
