Two version of speed
Version 1: A travels at 65mph, B travels @ 30mph
Version 2: A travels at 60 mph , B travels @ 70MPH

FYI Cop Chose version 1...I disagree...

Answer
there is no way to determine the actual speeds in a side swipe collision such as this one.  there is definitely one vehicle traveling faster then the other as they went bye each other but I would have to look at the photos of the damage to determine which vehicle was going faster then the other.  this only would give a speed differential and not determine which vehicle drifted into the others lane.
