as an aside, does anyone know if one of those scooters fat people use at walmart could outrun a zombie?
Max beat me to it, but it does depend on the director. Let's look at the reality, though... (Wait, did I just envoke reality in reference to zombies?!)
These things are (un)dead, and plagued with rigor mortis. They should have such inhibited movement that a Hoveround would be able to outrun them easily. heck... a tortoise should be able to outrun them.
