Noticed something with rush, that affects who is kicked. If two players are going at approximately the same speed in about the same place as they enter the box called, or even if one is behind a bit, whoever can be seen over the other one is kicked, even if they're winning. I figured it might be related to the thing where if two players are standing in the same place and you tap on them, it shows the profile of the one in behind... I think this might have the same effect on the finish line of races, too.  

Photo finish!  

Have you taken into account that the "winning player" may be lagging slightly more than the other person, and the other person in fact reaches the box first but you can't really see it?  

Thing is though, I've seen this happen with many players not necessarily including myself. Just thought this might be a bug, seeing as how I explained the way it related to a well known example, so... Ehh, I might be wrong, might not, just felt I'd throw this out here and see if anyone else had similar thoughts
