accidents

I think accidents/crashes should be added to make it more realistic but also a replay option of the races and overtakening to be a bit more realistic also the start of races could be like real life ones like starting in the grid ect thanks 

Yeah that would make it fun!

I agree

I definitely would like to see the aspect of crashes, especially if the driver is on aggressive. Also to have the racers on defensive prevent overtaking. 

I like this. Also with possibility of safety car

Agreed.  

Agreed accidents with sc would be a great addition and will shake a few leagues up 

I have both a feel of excitement and dread about the idea of accidents. As it would definitely make parts a valuable commodity.

Parts would need to be upgraded or an addition for car replacements! 

Maybe like engines you get x number of full car repairs per x number of races.  Say 6 or so. 

This game has a balance to strike, as do many, between three factors, practicality, realism and fairness on this issue. It's the old NASA triad. "You can have cheap, you can have safe and you can have it done quickly...but not all 3. Choose 2 and get back to me."
I choose practicality...(the game has got to run smoothly with minimal bugs) and realism, I want to 'suspend disbelief' and lose myself in the idea that I am actually running a racing team. 'Fairness', not as much a priority, the actual process of running a team throws up many instances of 'unfairness' as long as they balance out longterm...well that is part of sport.
