Vehicle physics are broken in this new update, you can replicate this by taking the s105 and turning on a flat surface at just 40kmh, the vehicle flips over, all cars now lack understeer, at high speed the steering is too abrupt/strong, at least add a speed sensitivity slider to fix this, but the correct way would be to bring the physics back to what they were on 1.6, there was no need to update them if it was to make them worse. another way to test this is to hit a small jump and steer, the car will not understeer at all and it will shoot in the way you're pointing.
