I would rather change the topic to cars being too dangerous. You see, people who drive cars like to drive fast. But sometimes they go a bit too fast, yes. At this point, horrible handling combined with enormous weight and poor brakes, becomes a part of the play. And add a powerful engine to the equasion (okay, the engine has nothing to do with this). The lack of control simply does not allow the player to safely escape the collision, instead the car starts tossing the player around, making it even harder to recover thus creating a collision hazard. The car becomes potentially dangerous after reaching 90+ kmph in straightaways. But in corners the speed has to be even lower, to finish the maneuver safely, due to the weight issues and high gravitational center. I suggest that we should adress this issue at first. About the /fix, it is genuinly a useful command, but lets face it. Someone will always abuse the weak points in the system. By removing the feature, there would be more losses to the players than trolls. From the other hand, by letting the command stay, there will be more advantages to trolls than the players.
