I'm a British/Israeli and will shortly be visiting Miami, Florida. I want to rent car for a week. Insurance is not covered by my credit card. From all I've read online, the policy I can buy in the US doesn't cover personal damage done to a third party. (I don't want to be landed with a $5 million bill for someone else's medical expenses) . Advice please. What insurance do I buy? Should I do it from Israel, before departure? From where? Any recommendations for car rental in Miami?
