Obviously you are too childish to realize the complaint is that this scene in the movie is a very bad example for children. Kids are impressionable and will think this is cool. This is not something adults want children to consider cool.
Hmmm...most kids don't drive, so I'm not too worried. I'm also trying to comprehend the idea of parents letting their children play around railroad tracks unattended.
Nevertheless, the argument I was making to begin with was that the man seemed to think that there should be no train track scene in the movie partially because it reminded him too much of his daughter's death. I mean...he doesn't HAVE to go see the movie.
There have also been quite a number of cartoons from the '40s and '50s, namely from Tex Avery and a few from I think early Warner studios, that did in fact portray cars racing trains and crossing tracks in time to "beat" the trains and having fun doing it. I'm pretty sure that there has never been an epidemic spanning from the '40s of kids actually trying that, and since I saw those cartoons myself as a kid several times, I know I certainly was never tempted to try it.
Then perhaps the adults, who inarguably have more control over the kids than Disney does, should teach the kids correctly.
Don't make a parenting issue a "social" one.
Obviously you are a prime example of being too stupid to be allowed to live by your self or allowed to vote. You should never be allowed access to a computer terminal because you are a mindless fool. Your group home supervisor needs to be reprimanded for negligence because he left you on your own.
