I've noticed a strange behavior while developing a robot.
When I manually perform coast downs (accelerate, then switch to neutral and coast down to zero speed), - the behavior is a bit different comparing to the case when I do it in robot mode. When doing coast down as robot, at speeds smaller than 7m/s the tires at the drive axle start jittering (it's visible at the tire chart and by sound), this also brings huge jitter in long acceleration signal.
I can't seem to understand why there is such a behavior and why it's different between human and a robot. I tried multiple cars and this behavior seems to be consistent.
Let me know if you know the reason.
