Modeling temperature might sound easy, but it is something that would make the game more of a pain in the ass.
Because it is a sim, you would not be able to feel the actual temperature. This would cause you to always have to look at a gauge to tell you. This would make it difficult to remember all the time and would cause too many odd things and big complaints. Not worth it if you ask me.
