I'm not convinced the glitch is harmless, nor that it is only manifesting in deliberately manipulated scenarios.
I did the Gallardo weekly challenge yesterday. The front wheel of the green AI car in front of me was bouncing up and down at very high frequency through the second corner, like a car with a broken damper (I haven't seen that on the road for over 30 years now, come to think of it). The AI driver reacted by driving really slowly. One corner later, the matt black / grey Gallardo, also while still on the track, was glitching sideways also at high frequency, while holding the steering at a crazy angle as the AI driver reacted. He was crabbing sideways in a very odd way. Both away from the apex then back towards it. The AI also slowed down a lot in reaction. My own steering wheel, in VR view, glitched a few times instantly jumping to maximum lock and back again. I was in a showroom fresh Gallardo, no tuning or mods. It was hard to tell if the steering glitch was doing something at the front wheels because since the patch I have found the transition from grip to sliding much more jumpy than before, almost like having a slow screen refresh rate. With understeer, instead of smoothly starting to move off line, the car often now just jumps sideways a couple of feet. Not all the time, often it's progressive, but quite regularly it is jerky. Most of the time the wheel turning in view was smooth and normal. I didn't save the replay, unfortunately. I crashed out (all my own work, I think) and restarted the race and had no problems on my final run.
The Jimnys on Eiger are ridiculous, lifting their back wheels off the ground under braking. My own Jimny was doing it too, on standard suspension and tyres.
Others are reporting sudden and unexpected snap oversteer, understeer and cars veering left or right all of a sudden. One noted that in the replay he could see his back wheels bouncing at high frequency at that point in his replay.
It's not frequent, but I think the glitch is showing itself all over the place and that is why reaction to the patch is so divided. Some are getting glitched in ways that are subtle enough that it doesn't feel obviously glitching, just feels like a bad or crude physics model. Others aren't getting glitched and are feeling only an improved model.
