Der Bayer: have you thought about incorporating drafting and (if downforce is eventually allowed) aero push? I don’t know how to calculate the length of a car’s slipstream, but something like that would both make for more passing and for more interesting dynamics with packs of cars.
Drafting is calculated, aero push not and never will be.
Sweet. 
Is this “bump draft”? If so, how can we ever hope to replicate NASCAR!!! 
I think bump drafting is properly the domain of the collision code.

Can you imagine replicating a 12 car pileup on a high speed corner? If people could punch each other through the screen…
