Something like this could be partially implemented. Say in the classic scenario of one ships docking via auto-pilot when another player tries to zoom past on manual and they collide - 100% the player under manual controls fault there. Equally, though trickier to check for, if one player is proceeding slowly through the docking port (i.e. at the port first) and another tries to zoom through - both player being on manual control - then the zoomer is liable. Should help discourage impatient players bullying the more cautious by ramming them out of the way - especially if the former is in a larger ships and the latter maybe just starting out.
Doubt it'll happen, but fining the offending player (or AI, let's be fair) to recover the costs of the victim (if they die / take damage)has some merit.
