Hot tire pressure

Why not just get a set adjustable tire pressure relief valves and it will always keep your tires from exceeding a set pressure?

Those sound pretty neat, but what if you have an error and make a big slide and temporarily overheat the tire, raise the pressure which is then released by the automatic valve, then the tire cools down and you are now too low. To the extreme, this lowered pressure could increase friction and heat, raising the temp more, pushing out more air. Etc. also seems like an extra part to fail and then.let all the air out.

Now if it also had a batmobile type capability to add the air back in.... Then I would be all in. Tell the computer to set each tire to X pressure and have it stay there

Its not always as simple as "set and forget".

For example, in the fall the high temp will be mid-day but late afternoon sessions/races could be quite a bit cooler and that may actually require that you add air in order to get the tires to the optimal pressure. If you rely solely upon the pressure relief valves, then you could be under pressure for the latter/cooler part of the day.
