This was a fantastic video. Thank you for posting this!
Since the maximum force with which a car can push against the road is limited by the friction
coefficient of the tire multiplied by the normal force, it is clear that Tesla is now approaching the maximum acceleration possible within the confines of the laws of physics. The only way to improve acceleration would be with racing slicks or thrusters.
If you do an apples to apples comparison you quickly realize that the standard LR Model S will do 0-60 in approximately 2.85 seconds with 1 ft of rollout. The acceleration benefits of the plaid are definitely restricted by traction at lower speeds. It makes one question the value proposition of paying 40K more for the plaid to gain 8/10th of a second to 60. The clear benefits will be achieved with passing power at higher freeway speeds.
