The maximum allowable height rule for the CA
mobile shootouts that I attended was 12.5 feet
from the ground. Don't know if that's the CA
limit or not.

CA limit is 14 ft (unless you have a "moving permit")
Pilot cars can have a measuring device that's taller, as long as they
don't go slower than 20mi/hr below the speed limit. (presumably this is
in connection with the moving permit for the oversize load that's following.

Your friendly local CHP office will work out the route for you..
