I agree. I also like the part when the cars start galloping like horses!
In reality though, there's no way cars could follow along with a train like that. The ROW is not that wide and there is usually too much debris, swithstands, and sidings to drive over.
I liked the video, I thought it was very good and very original, it had a Terminator 3 kind of style about it, with the driverless emergency vehicles everywhere, I was expecting a huge crane to come out of nowhere and smash everywhere up...
