The issue is NOT overblown. You are solely responsible for lost wages. There is NO insurance available for it. Period. I don't see that as overblown, but a big liability (however slim/slight or small it may be). An attorney may help, but you are still potentially responsible for hundreds or thousands of dollars.
This is not an isolated incident as I have had this very thing happen to my wifes uncle in 2009. He got out for cheap due to his federal connections, if not, he might very well have ended up like the pastor.
In the US, as a car renter, you can get full coverage with extra limits that will essentially cover you for just about any type of accident. Same goes for Europe and other major countries.
I will no longer rent for the week, BUT I would consider a day rental from someone like Isis just to make the trip to the East side.
