God WA how I've missed you.

One thing that's bothering me is this whole behemoth keep up with the truck, how? there slow. The trucks sounds like its going fast. Is it because Victor was laying of the gas from fear of crashing or the stuff on the ground is slowing him down?? Whatever the truck dodges would slow the behemoth down right? Seems strange to me. I like the idea that the who/what is creating them is making improvements. Sounds scary as hell. Or is this just my case of over-analyse
