Here is my analysis in four frames, based on the section âOvertaking on the inside of a cornerâ from the F1 overtaking rules. See here for an example. As far as I know, there are no detailed written Race Regulations for Forza Motorsport, so I base my analysis on these.
The overtaking car needs to have a significant portion of the car alongside the car being overtaken. âWhen considering what constitutes a âsignificant portionâ for an overtaking maneuver on the inside of a corner, among the various factors that will be considered by the stewards when exercising their discretion, the stewards will consider whether the overtaking carâs front tires are alongside the other car by no later than the apex of the corner.â
When we examine frame 1 (02:18:583), we observe that moment: itâs well before the apex, and there is at least a gap two cars wide between the white car and the track limits. A quick note here: this is roughly 2 seconds before the collision occurs.
âIn order for a car being overtaken to be required to give sufficient room to an overtaking car,â Frame 2 (02:19:302) shows the red car already ahead, with the white car still providing enough room, as is required by the regulations.
â⌠while enabling the car to clearly remain within the limits of the track.â Frame 3 (02:20:223) shows the white car reducing the space for the red car, not leaving at the very least one car width for the red car within the track limits. While the red car goes over the track limits (not penalized in Forza Motorsport as long as one wheel stays within the track limit), the white car is still required to give it room, but fails to do so.
Less than 200 ms later, the collision occurs. Frame 4 (02:20:407) depicts the collision and how it causes the red car to rotate to the right. Itâs also notable that the last two frames show that the red car was not faster than the white car, since the overlap remained roughly the same. Upon close inspection, you might recognize that the red car even fell a few inches behind, indicating less speed. Arguing that the white car could have made it safely through the corner at that speed, while the red car was too fast, surely has no basis.
The collision was caused by the white car, as it did not honor the racing regulations as demonstrated above. There was also enough time for the white car to react, as the situation unfolded.
