The cars in GPL, 1967 F1 race cars, rearward weight bias, no downforce, high
working slip angle, are probably ideal for using induced understeer. I've
read that the Lotus team manager heard Jim Clark describe using induced
understeer, with the manager responding, that's why he's a manager and not a
driver.

I've asked some club level race drivers about using induced understeer, and
although it's not needed on most cars, there are a few where it's used.
One guys comment is that his Clio was evil, and he had to use induced
understeer, to keep the car in check on high speed turns as I mentioned.
Most guys that get to run their cars on ovals for fun end up getting large
rear wings to keep their heart rates in check.

GPL did have a induced understeer quirk, on the Lotus, if braking balance
was around 53%, you could get a reverse steering yaw reaction when braking
hard. Also using front toe out could be used to keep a car stable under
heavy braking. I made a video of the reverse steering reaction, although
the video only shows a left yaw, I could steer left and get a right yaw
on the same section of track:

The worst "offender" of induced understeer was with LFS S1 all or nothing
grip factor, especially on the LX6:

Induced understeer used properly (just a bit) and coutner-steering, Rouen
by Greg Stewart. Tires inwards while slowing, outwards while accelerating,
inwards on the very high speed right sweeper. After the 90 degree left
haipin, the next two acceleration right turns are done with the steering
spending most of the time left (throttle oversteer). The bottom (chase)
view of this video give you a good idea of what is going on.
