What is the best 60-to-0 time for a road car? If traction is the limiting factor, you should be able to get very close to that same time in the reverse direction.

Edit: the shortest 60-to-0 braking distance I find claimed is for a Dodge Viper ACR (Mk 5) at 87 feet. Assuming constant acceleration, that works out to 1.98 seconds.

There's an Engineering Explained video that takes this approach:

They estimate 2.0s is roughly the limit on standard tires, F1 cars can do it faster due to stickier tires.

He also has a video about Tesla acceleration:

Which talks about whether the Model S has an advantage over the (old) Roadster due to the heavier vehicle gripping better.

Interestingly the number he calculates for a theoretical roadster car is very close to Tesla's new number.

They also have a video about "rollout" which can alter 0-60 times and needs to be taken into account for comparisons.
