Looks like it is simply a conspiracy theory against GT more than anything else.
As far as graphics; perhaps my eyes aren't as keen as the eyes of others here, but I don't see much of a difference if at all.
The crashes don't seem to be very important at all. They just showed a smaller crash on the PS3 version; it doesn't mean that the PS3 can't handle larger crashes. Again, this looks more like a conspiracy theory attempting to state that GT has ulterior motives.
As rocketpig stated, editing together a good video is not always easy and making a simple mistake can happen. Again, I call nothing more than a conspiracy theory on those who say that the proof is the button symbols in the video.
Now, having said that, could GT be actually intentionally making the PS3 versions of games look worse than the 360 versions? Yes. Are they? I say, probably not.
