the series sounds good but i see 2 problems, firstly there is no way that i nknow of to see a drivers fuel amount so you could never know of a driver was using the correct fuel level also the problem wth formation laps, there is currently no way to do it properly, it can be done with insim but needs alot of programming to remove probels with lag and even then it is still not great, as far as i know only becky rose made a system to do that for the stcc series but it was never used.
