I often travel to the UK with a group. Last year when I looked into car rental, I was surprised to find that only Hertz offered personal accident insurance (insurance that would cover medical expenses if something happened to anyone inside my car in an accident). Most of the same companies offer that insurance option in the US, but not in the UK. Enterprise, for example, told me that I should look into travel insurance to have that covered. I couldn't find any travel insurance that would cover rental car accidents. My car insurance won't cover personal accident insurance in another country.
What's the deal? Is it because the NHS covers UK citizens for that sort of thing, so they don't bother offering it for visitors? Would the NHS cover any of us in the event of an accident? (My initial research says they shouldn't, but please correct me, if I'm wrong.)
Thanks for any help you can give! I really would prefer to have more options than Hertz - I had a bad experience with them last year.
