The comments on this video are insane. Apparently people believe that the guy taping it should have gotten out of his car and run over to save the cat.
These people have obviously never tried to get a real live cat to do anything.
That cat was not ignoring the train. Clearly the sound and rushing air (and possible slipstream) annoyed it greatly, and it decided to walk away. For a cat who frequents the area, I presume this would be a fairly well known phenomenon. -2 stars.
