Found this interesting part in the Digital Manual of Gravity Rush:
Do not use or store the game card in the following locations or under the following conditions:
- In a car with the windows closed (particularly in summer)…
It doesn't makes sense to me why you shouldn't use the game card in a vehicle with the windows closed. The other ones make sense like in direct sunlight/heat sources (deforms plastic) and high humidity/corrosive environments (causes corrosion), but specifically using or storing it inside of a vehicle does not.
Why shouldn't a Vita Game Card be used or stored in a vehicle with the windows closed?

The full bullet point says:
Emphasis mine.
As you can see, this bullet point clearly relates to heat. We're not talking about the boiling hot temperatures still within operating range of a modern desktop CPU, which is around 100°C (212°F). We're talking about the temperatures an object can reach when subjected to direct sunlight.
We're also talking about the temperatures inside a car, which is sometimes left under direct sunlight (much to the misfortune of children and pets), which according to The Zebra can be significantly higher than the temperature outside the car:
Now imagine how hot the inside of a car can be in summer, when outside temperatures can easily surpass 30°C (86°F). According to Driver Knowledge Tests, very hot:
And as we know, PS Vita cards, too, are black.
For the reference, here's what National Instruments has to say about how temperature affects flash storage:
When in use, the card is likely going to have much stricter temperature tolerance. According to Delkin Devices:
With the PS Vita card being a proprietary flash storage medium, it's hard to give any specifics, but it's unlikely to be industrial grade. And if the manual says not to use or store one in a car in summer, that's probably for a very good (heat-related) reason.
