So, the car in front can actually benefit from the car in the rear

Hope to see that in LFS some day

So that's pretty much how Nascar works. Nothing new tbh. But yea it would be nice to have something like that in LFS.

Of course this effect can't be added in artificially, so we'll have to wait for an updated aero model, which will probably (hopefully) include underbody areo effects and breakable wings.
