Ok, it seems I misunderstood what DISRUPTOR meant.
I thought he was saying that collisions online were fine and shouldn't be modified (which is a lie, they are most certainly not fine for anyone, thus my reaction.)
He says that you can hit other ships to try and get them out of the way. Ok, that's something valid. However there are still problems with that in online races (In offline races it works) so it should still be slightly modified.
All in all, it comes down to lag, because like I explained earlier the ships positions on your screen in online races does not necessarily represent the actual position of the players in the race. So there's the problem of trying to hit another player and actually hitting them.
And then, there is the damage output, which is way too high. Sure, like DISRUPTOR said, you can deal lots of damage this way, but it is still incorrect compared to offline races where the damage dealt is much less, so this should be modified.
Finally, there is the fact that steering out of such a lock is nearly impossible, I have tried this many times whenever it happened as many others no doubt, and it doesn't seem to work. This should also be modified as to be correct and just like in offline races where it is possible to steer away from other ships colliding with you.

So sorry for the misunderstanding.
