A while ago, Kenni, Jomas and me have figured out the collision penalties could be exploited while fooling around in a lobby. I remembered the bump drafting giving SR downs to the car in front and some observations I've read here and there in the past and came up with a theory. We did extensive testing and research in private lobbies on several tracks, and decided to sum up our findings in a video (please excuse the baguette accent). I'm releasing it publicly now because we found out one person had figured out the exploit and started using it in daily races. This is not something we made to promote cheating, we're calling for all drivers to act responsibly on track and not use those exploits to gain an advantage or retaliate (always check your replays on incidents before blaming people). Note that the following is true in all sport mode races, including FIAs, as recent examples seen on videos and streams prove it. To sum up : - when the game detects a collision between 2 cars, it will use speed differential after the contact as the criteria to decide who is to blame. The car who is slowed down the most following the contact is considered as the victim. Steering, braking or throttle inputs does not matter. - in case of a bump from the rear, the car in front will always be deemed responsible, with the only exception being if it's immediately sent into the back of an even slower car. - in case of a side hit or t-bone, it can go either way. In all my attempts at side-swiping Kenni in the video, the energy from the contact was translated mostly sideways, which made his driving wheels sliding, and the speed on his speedometer dropped because of that, making me get the penalty on those ones. - the trigger for the penalty to actually happen is the "victim" car going off track (this includes hitting a wall). - the amount of the penalty seems to be determined at least partially by the speed gain / loss difference after the contact, with the penalty being capped to 5 seconds. - once the game considers you're the victim, you're basically immune to corner cut penalties for a short moment. Now let's analyze some recent incidents that popped up this week : >>> [FIA race] In this one, the Megane gets a 5 second penalty out of nowhere after the Corvette wipes out the poor NSX. Why this happens : in this situation, the Corvette is sliding accross the grass, and the game sees that as a loss of control, so this car is basically immune to contact penalties. Now the Megane gave a lovetap to the NSX right before it got sent to Narnia : while in most situations the NSX would have taken a SR down from that, the hit from the Corvette happens quickly enough after the bump draft that the game still thinks it's the same incident, and as the NSX has lost all its forward velocity, it has lost much more speed than the Megane did for the game. Since the NSX goes off track, penalty is triggered. ------------------------- Tweet removed due to profanity >>> [FIA race] Here's an example of a side contact giving a penalty to the car in front. Atho and Stefounzy have a minor contact, which sends Stefounzy in the grass and brushing the wall, making him lose speed in the process. No ill intentions there, but a very harsh 5 seconds penalty handed out to Atho. ------------------------- >>> [Daily race] Perfect example of the system being actively exploited in sport mode. A school case.
