This is so true.
I live in the desert, and it's amazing the number of people who simply don't take the natural world seriously.
The dead and rescued are almost always tourists. And for some reason, almost always from Europe (I suspect because my observation has been that Asians tend to travel in large groups on air conditioned buses). They drive rental cars into deep sand and get stuck and die. They run out of gas and get stuck and die. They never bring enough food or water and don't know what to do in an emergency.
I was at a hotel on the Navajo Reservation (Arizona/New Mexico/Utah) about a year ago and there was a British couple arguing with the manager that of course their cell phone should work, they bought it in San Francisco. I tired to explain to them that the whole reason people visit places like this is to get away from technology. Even though I'm sure there are remote places in Europe, they had no concept that there are places in the world where there's no cell service.
A couple of years ago there was an article in the newspaper about a German guy who decided to rent a Harley Davidson and drive through the desert like some kind of David Hasselhof fantasy. It was 115° and he was in full-on black leather gear. They found him dead on the side of the road, still sitting on his motorcycle with his helmet on.

Editing to add the results from a four-second Google News search:
authorities in California launched a search for Pi-Wei Hung, 40, early Sunday afternoon... the woman’s vehicle was discovered stuck in the sand on the shoulder... and then died in the heat as she tried to walk out of the area. The high temperature that day was 113 degrees.
a 60-year-old tourist from Germany died from heat exposure... not far from his where his motorcycle was parked, upright and in working order, in the 118-degree heat.
...two French tourists got their car stuck in loose sand... no one knew their specific travel route, and they were out of cellphone range in temperatures above 110 degrees.
