What about addressing the rules that allow drivers to intentionally run cars trying to pass off the road in order to prevent them from passing?
CCR (See 25.4 page 79)
According to the rules the car doing the passing is responsible for any contact; the car being passed can chose any line he likes including one where there is already a car there regardless of how far up alongside the car is or however long its been there; you are not considered lead car until your rear bumper is ahead of their front bumper; and the car being passed is allowed to push you 1/3 car width off the track on inside or outside, in a turn or a straight. Blocking is 2 consecutive moves, so moving over to push someone off track is not considered blocking.
Given all of that, what in NASA’s rules prevents someone from swerving into a car trying to pass in order to prevent them from passing? It looks like this (2nd incident at 22 seconds mark) would totally be legal in NASA. http://www.youtube.com/watch?v=E3nSOKdTWuQ
Here are some incidents from NASA where the passing car was deemed at fault, even though car being passed intentionally moved over.
This accident was first deemed 100% passing cars fault, even though lead car knew he was there and moved over intentionally in hopes of forcing the passing car to back out.
(lead car view)
(passing car view)
(watch review mirror for red and white cars)
(Camera car never gets fully ahead of red car, and therefor deemed 100% at fault, even though red car pitted him).
(camera car never got fully ahead of Miata, so when he was about to complete pass, Miata hits him, and therefore camera cars fault).
(here you see a car getting passed trying to push the passing car out into the grass even though he has plenty of room to the right, passing car doesn’t give in and car getting passed touches passing car, ends up taking out a whole bunch of cars. Not sure who was faulted).
Here are some discussions on the incidents.
