I couldn't agree more with this point! In my opinion the player needs to move slightly faster than the zombies so that in a straight out sprint for your life you can gradually make ground between yourself and the horde. I also think that the zombies moving in more of a lumbering run would be better than a full on sprint, not only mechanically but also visually. Being the brain dead, uncoordinated things that they are, they could also occasionally stumble and fall affording you some valuable seconds to escape. and once putting enough distance between yourself and the zeds they need to give up. On a side note it would be great to be able light a flare straight into your hand (rather than throw it and pick it up) while running. so when being chased at night through the woods you would at least have a chance of seeing what your up against, and turning to shoot them down. That is all. :)
