The problem here is that in real life, the driver can just turn on the radio and ask the pit crew about his tyre temps, what sort of compound they're planning on putting on next, how much fuel they're going to put in next round, what his last split time was, what his current time is, etc etc. In LFS though, you don't get that luxury, and the ingame readoffs are the closest thing to a pit crew that we'll probably ever get.
