Ice mode is not a Camaro specific feature, all cars with ABS have some version of this for the above reasons.
I don't see a big enough difference in left to right speeds to cause this. If you look earlier in the video, you see lots of lower speed corners while on brakes. There the left to right speed is much higher due to large difference in radius between inside and outside wheels. In the video he started braking more or less in a straight line. Hard pedal indicates ABS experiencing big slip, OR big difference between measured wheel velocities and reference velocity of the vehicle.

Yeah dunno, I got no other way to explain it. I've had the exact same feeling before in turn 3. Both turn 11 and turn 3 are the only places on the track where I start hitting the brakes with steering input on the wheel. All the other corners at slower speeds while on the brakes, begin with braking in a straight line for a good amount of time. Could be something else but I don't know what it would be. It's something i'll keep in the back of my mind. I've been to VIR now 7 times and I've only felt it twice, one of those times going off track. So it's certainly not something very common.
