We have a similar problem with tourists in Australia and people (even from the US) underestimating quite how large the country is, and how you can very quickly find yourself on roads not meant for campervans and regular cars, and on roads that rarely get travelled. Last year about a few hours drive south of Sydney I found a very young German couple who were on a otherwise completely deserted and unpatrolled beach. They walked down from the parking spot to the beach and spent a few minutes wading around in the water. After speaking to them, I found that they'd flown into the country the previous day, rented the van that morning and this was the first beach they had found. They said the only thing that kept them from swimming out was a worry of sharks. I had to spend a few minutes educating them about rip currents, and pointed out that they'd just been wading in what looked like the biggest one on the beach.
