"I don't know if the problem is tire, differential, or momentum
modeling
in GTR that is the issue, but the issue is that almost every low speed
spin results in the car facing backwards, as opposed to real life where
ending up sideways occurs just as much, if not more than backwards. "
If you want controlled slides in GTR here's a way to do it (probably
not the ultimate, but good ebough for demonstration purposes). Use
Dunlops (the others will heat up and lose too much traction. Springs,
shocks, and bars reasonably balanced. Max neg camber on front, small
negative camber on rear. Hard compounds. Diff max power, min coast.
Have a ball. You'll wind up sideways as well as backwards. Of course,
it's not a fast setup. An underappreciated quality of excellent
drivers is that they can drive fast setups that punish mistakes _right
now_. It's especially true in NASCAR. One big reason the guys at the
back of the pack are slow is that they can't drive a faster setup.
"In real life, you can take off spinning both tires, and it's
reasonably
easy to keep the car going forwards. "
You can make real pretty twin tire marks with the above setup.
"There's a Top Gear video where Tiff drives a 4 year old Ferrari
formula
1 car (a Ferrari F50 is also tested in this save vided), and even in
his
first time in the F1, he lost the rear and and recovered quite a few
times
in the video. He was able to drift the car fairly well at low
speeds..."
Tiff's lurid slides on Top Gear are a running theme (or a running
joke?). It's especially a hoot when he's supposed to be driving fast
on a track. Sideways ain't fast, just entertaining TV. I would
imagine they mess around with setup, tire pressures, etc. to put on a
show.
If you enjoy GPL, fine. But to say it has better physics than GTR is
silly. The relative responses to setup changes and control inputs are
concrete proof. There's also logic. Do you not think the guys who
did GTR are smart? Do you think they didn't bother to analyze GPLs
physics for strengths and weaknesses and incorporate the former and
reduce the latter? Do you think they didn't use increased CPU/video
card processing power and technical information from GT race teams to
do it better?
