I take your point but to me this seems like a feature rather than a bug. Many of the plastic parts in most cars (not just Teslas) are degraded by oxidation in the greenhouse heat of the car being parked in the sun for a long time. Some of that oxidation is caused by UV, but to the extent that it's caused by heat, keeping the interior of the car somewhat cooler should prolong the life of its interior plastics.

This is not really an option in an ICE car because it would require running the engine. In an EV, it's easy.

vinyl and plastic degradation is a many years-long process before it has any real impact on the performance of the parts. Failure or yellowing of the non-automotive grade screen in a model 3 has been seen in just a few weeks or months.
