Default GTR: You must be kidding me

That explains it.

If you look at actual lateral force versus slip angles there's
not much, if any loss in laterforce at higher slip angles, except
for the fact that tires get overheated. Avon is one company that
publishes this data, and Todd Watson, who has been working on
basic simulator physics, has done a lot of research on this
consulting experts, and there's little loss of grip at higher
slip angles, it's just the lateral force is not quite in the right
direction.

It also depends on tire contruction. IRL (Indy) cars have the
smallest "working slip" angle of about 2 degrees. F1 and Cart cars
are more like 2.5 to 3 degrees. Most non-downforce racing cars
wihtout tire restrictions will use bias ply slicks, with a slip
angle around 4 to 5 degrees.

Yes I agree with this, I feel that some aspects should be
compromised to make up for the lack of feedback. Traction control
is one way, and realistic, since it's used in FIA's F1 and GT1
classes. Champ cars don't use traction control, but looking
at videos of events at Laguna Seca and Brands Hatch, there are
a lot more incidents than in F1, maybe fun for the spectators,
but not the drivers and teams.
