In a sim as complex as this, there is really no need to ridicule people asking questions. I've been racing this title every single day for two years, and I've asked tons of questions and I still don't know a fraction of what I would like to know. I'm still learning. So please lay off with the laughing and ridicule, it helps no one. Real Road is incredibly complex and no other title has anything that even resembles it. No wonder not everyone completely understands it.
