An iPad is not going to survive in a parked car in the hot sun. Supposedly that's the reason that Tesla's have the "dog mode" aka "Cabin Overheat Protection". Their cars will cool themselves down to prevent the big touchscreens from being destroyed by high temperatures.
Strange - one of my former supervisors had modded his truck's center console to use a Android tablet of some sort (don't recall which one, but it was fairly high-end - maybe one of the Samsungs) - it was basically "built-in" and non-removable; in fact, if you didn't know, you'd believe that it was OEM (it was a very clean install he'd done).
I'm in Phoenix, Arizona - and even in the middle of summer, with the sun beating down and turning the inside of every vehicle into an impromptu slow cooker (seriously - you can slow-cook in your car here in Arizona; that is, if you don't mind your car smelling like a working kitchen afterward), the LCD never had any problems that I could see.
I was honestly very surprised, as LCDs are normally very temperature sensitive (more to cold than to heat - but I would think that the temperatures inside a car in the summertime would be hot enough to cause problems). Usually, though, whatever the temperature - if the LCD has problems, once it comes back within it's normal range it will start working properly again.
Wherever that “supposed” claim comes from is BS. They have the dog mode to prevent dogs from cooking, and you explicitly enable it when leaving a dog in the car. Hence the name.
