In cars with a heavily biased open diff. If an open diffed RWD car is 90deg sideways to the left (Extreme example), and you're pinning the throttle, the left rear wheel will be spinning (Unloaded) and scrabbling for grip. At these angles (In basic terms) this scrabbling for grip will be trying to put the car negative 90deg while the loaded tyre is simply scrubbing laterally and reacting to lash in the diff vs grip. But! I do agree with the points/ @SlowPoke80 The issue is the amount that this happens, the extremity of it is way over the top IMO, by a large amount. And especially so in anything where the diff is more locked under power. Edit: Just to add, that of course this is very car/setup dependant. Oh and I do believe that the devs are always improving things, I'm not worried at all because as it stands, it's still a damn good overall package/game/sim even at this stage.
