Just thought I'd point out that the crazy barrier collisions have been massively improved in the latest version of LFS. Numerical discontinuities are fun!
It is sad though, when I think back at the fully-formed sense of physical interaction (although still often glitchy in "high energy" situations, or online) in games of GT's vintage like
GPL or
Carmageddon 2, that we're still not getting that with GT. Mind you, it has come a long way.
And whilst I totally agree that the end result is important,
Zevious Z, it doesn't take very much for the suspension of disbelief to be broken by GT's frankly odd collision / solid body physics, and it points to a fundamental shortcoming in the overall physics system.
Maybe it's part of the reason body pitch / roll is so slow and under-represented, or that the low speed physics are so screwy, or there's a lack of any real drivetrain interaction with the road, or that jumps are self-levelling. Were all of these to be "fixed", it would make for a better simulation experience, so hopefully all of these will be addressed in turn; unless there's a fundamental reason they can't be with the current system.
Let's not forget that there are plenty of situations in real life that at least one wheel will come off the ground; e.g. most FWD cars cock a rear wheel in the corners, and some older FR cars would pull the inside front wheel up in corners, too. GT exhibits neither of these traits in the appropriate cars, either.
It's come a long way, but it still has some way to go yet.
