Cabin overheat protection is designed to protect the electronics in your Tesla. Tesla, in their wisdom, decided to use "industrial level" LCD screens instead of "Automobile level" LCD screens when designing and creating the Model S. This was Elon's smart move, and turned out to be a really bad idea. Industrial level screens aren't able to handle the temperatures that automobile level can. This feature was released to help protect the electronics, mostly the screens, that were failing because of the heat.In fact read this article about Ford's proving grounds... Particularly the one they use in China. It says they have a sunload chamber to recreate the car sitting in the baking sun... It says interior temperatures of the car reaches 224 degrees F. So yes... 145 degrees F is nothing.... It says they have engineers wearing special suits to protect them up to 392 degrees F. They interact with the components in the car, and says that any bubbling or deformation that happens at 224 degrees is rectified and corrected, so that customers will not face these issues.
I assume by now they are using proper screens (but I am not sure), but regardless, the feature was designed as I mentioned, to protect your car, and not for your comfort. The end result is that it helps both scenarios. But your article about Ford is irrelevant given the route Tesla took.
