Many times when a car gets sideways in real life, after correcting the
slide, the car will swing back the other way in a series of fish-tails,
or "tank-slappers".  I don't believe I've ever experienced this in GPL
and all of a sudden I'm wondering why?

Coming out of the 2nd lesmo is way too easy to fish tail ,   just especially
if u get on the metal too soon  and lift off quickly

What sort of wheel are you using?

When I used my old T2 I never had any fish-tails, but with my Wingman
FF i get it quite often.

I guess it is because the forces in the FF-wheel makes the wheel react
more realistic(wheel moves by itself reacting to frontwheel direction
etc) and therefore causing the car to fish-tail. There probably is some
more "physical" explanation for this, but I don't know it! :)

Your not driving hard enough. ;)
I think the tank slappers are caused by you getting behind on your
steering. It is easy to do. Your counter steering hard then the rear
tires get grip and snaps you around the other way then you counter
steering the other way and then the rear wheels grab and throw you
around etc... then from there your fight the car and trying to catch up
in the steering. It's a driver error if you get into a tank slapper.

I think the reason why we don't get much of them in a sim is becuase are
wheels are small and only have a limited turning range, so it's quicker
to turn the wheel, you have less chance to getting caught behind in your
steeering(Mr. Slowhands).
Nascar Drivers are famous for tank slappers becuase they have a 10 foot
steering wheel and it turns and turns and turns. Plus they are used to
turning right. :)

Really easy to fishtail when you first go from single axis pedals to dual
axis... come off the gas.. induce power off oversteer  (the car gets
loose).. panic!
       It works for me!

You're not tiding soft and high enough... they sometimes do for me (usualy
while I'm leading... ouch!).

Maybe because you're such an excellent driver? <g>

I've fishtailed in GPL plenty--often followed by a resounding crash.

I agree.
You can make the effect by putting the power down too much out of a corner
but unfortunately there is not fish-tail effect from correcting your turn:-(

The reason is because in most cars you drive on the road are NOSE HEAVY. and
in GPL the cars are HEAVY in the TAIL. So in GPL the back end will keep
swinging around until you do a 360 and not fishtail.

I can tell you, I have an FF wheel and in GPL I *do* experience this.

With my LWFF I get all the fishtail effect I ever want to feel, as the
tires catch and slide and you have to work the tendency of the front
wheel angle causing the rear getting out of shape on the rebound as the
rear tires catch.

It feels pretty realistic to me compared to the fishtails and donuts I
used to do in my old rear wheel drive '67 Chevelle I had (and abused) in
high school. Of course my front wheel drive Honda doesn't do any fun
stuff like that, but at least I can still do that in GPL.

Are you using an FF wheel?

I use a constantly-in-a-state-of-repair Thrustmaster Nascar Pro
wheel/pedals.  I set all my setups to 15:1 steering ratio, and recently
changed the core.ini to eliminate the variable ratio steering below 60 MPH.
 (Boy that takes awhile to get used to after driving the other way for so
long).
How does having force feedback affect your lap times?

Well I've a MSFF and midpoint at the parabolica right towards the end
is when I experience fish-tailigin if I fail to stick to my line. Also
I am guaranteed fish-tainling at the start of races if I get too
e***d with the throttle.

  Are we talking about fish tailing - the wagging side to side of the
rear end of the car before either disaster or miracle recovery - or
just getting sideways.  I very rarely get actual fishtailing anywhere
except out of Lesmo 2 at Monza.  I assumed it could only happen under
power on where the front has plenty of grip but the rear hasn't.

  Anyone able to actually explain fishtailing?

you gave yourself away when you wrote "tank slappers".  You've raced on
two wheels too much.  As you know, when a cycle gets out too far, it's
not the same as a car, in the car you just peddle and use the wheel.

On a ***cycle,  your weight loads the suspension when the rear tire
finally grabs,  that's when a couple of ugly things happen.  You might
get spit over the front or get one or even two more tank slaps before
getting spit over the side.  The two wheel question is not how to stop
the slap (because your body is causing the problem and you probably
don't have enough control over your body at that point).....but before
all this happens...(cus you been in the corner before)  flat trackers
pull left foot off and lean foreward to keep the back wheel from
grabing abruptly,  moto-xers do the impossible and stand up and lean
foreward & keep the throttle wicked up.. ssshhhh,  and road racers just
do 2 tanks slappers and crash.  Oh,  you won't find this happening in
speedway,  they don't use much suspension.
