I think I'm pretty hardcore hotlapper with around 20 hours of hotlapping this week.
Imo optimum temperature would work only for slow cars/short tracks. On any other combo optimum temp is pretty useless. If you start lap in GTR car with optimum temperature tyres, your tyres will be dead after few corners. For me only slider bar makes sense.
Also, to get the best possible result you would need own slider for every tyre. For example, FWD cars need more heat for rear tyres than front tyres at start because front tyres heat up more during lap and vice versa for RWD cars.
I hope this isn't too impossible to make.

Tyre heating is very annoying and time consuming so even some kind of relief would be great.
