It's not that it gives unfair penalties to high rated drivers (not at the moment anyway), more so that lower rated ones (B and below) do not have to drive to the same standards and rules and do not get these deserved penalties for doing the exact same thing to each other. Then if you end up with a mixed room it'll let the B rated driver punt the A or A+ driver without penalty more often than not.
At one point (probably more) in Sport it used to even give the A rated guy the penalty for it. I think
@Sven Jurgens even used to deliberately lose Dr sometimes to stop this from happening, as he was getting lots of unfair penalties when the B drivers were constantly hitting him yet since he was A rated it was always blaming him.
