Yes, but ABS systems can be installed alone, without any other stability
stuff, and that's the way my car was ... I think. I'm pretty sure it had ABS
because there was a light on the dashboard for it, but it didn't have any
stability weirdness. As I recall, the light came on when ABS was engaged. Of
course, it never came on for me, because I never stopped recklessly enough for
it to activate.

Non sequitur.

I'm afraid not. You've admitted yourself that many differences are trivial and
can be easily adapted to, which is true. Moving from sim to airplane or back
is the same way. Only an exceptionally stupid student or pilot would not
notice and allow for differences between the two.
