I have to say, while it would be an improvement as to make it more into a simulation (which I normally would support enthusiastically), personally, I detest the idea of the safety car and how it ruins a race. It might have become necessary in this day and age where safety has replaced the recklessness of yesteryear, but imagine driving a perfect race, getting 20 seconds in the lead and then 2 AI cars crash and you're robbed of your lead. Never will that much swearing have been heard before.
So, bearing in mind, this is a game and noone needs to be saved from a crashed vehicle, please just let the cars race to the checkered flag without boring us to death behind the safety car and ruining a good race in the process.
