For a moment the program forgets what kind of grenade Lapine threw, or else the programmers made some kind of mistake. Flashbangs shouldn't be making salsa, much as that does count as distracting and incapacitating people.<br/><br/>It does correct itself -for a certain value of correct-, but that was an interesting thing to see, and might instead have just been the outside and walls not being properly accounted for since the 'gap' between cars is a bit abstracted. You can see it, but not be in it, probably because the motion is currently set on smooth and any chance of derailing or decoupling is out for various reasons.<br/><br/>That said, the point was to clear a path and nobody could deny that there is now a clear path if you ignore the disappearing virtual giblets.
