2) It removes a thin layer of aged hard rubber,
and reveals fresh soft sticky rubber.
If it removes a layer of rubber wouldn't that also remove the TrackBite?Â
They spray the track with TrackBite, not
the tire. You do a burnout principally to remove
this aged layer of rubber,
Years ago when I was paying attention to this stuff, road racers on slicks
could pull 1.2g and higher without any special 'TrackBite'-like coatings on
the track. I remember 2g in some situations, but I don't remember if
banking was involved.

Ordinary pavement in contact with rubber tires give a coefficient of
friction of about 1. There is no getting around this. It limits the
acceleration to about 1 g, which translates to a 0 to 60 mph time of
about 2.7 to 2.8 seconds. To quote the BMW owners manual on the subject
of traction

Nor will TrackBite alone get you there without heating the tires and doing
the burnout. Both are required with a car producing 1000 horsepower or
more.

The reason that Tesla is limited to a 0 to 60 mph of 3.2 seconds is that
you can only get about 1 g of acceleration on the street. The
coefficient of friction (on regular pavement) is a little less than one.
I'm guessing that the 2 second 0 to 60 mph time is calculated using a
simplistic
