If you are racing for 28th, stage points are pretty irrelevant. The thing about drivers from other series is that most are either coming from series like IMSA, where you will likely be heavily penalized for rough driving, or F1 or Indycar where contact likely means you will be knocked out of the race. In NASCAR, especially with the new car, there is actually very little risk to driving like a total a-hole. The car is hard to damage, NASCAR likely will never penalize you, and none of the drivers have the grit to go whip your ass for doing it.
