1.) I don't drive an F350.
2.) That passenger space is not intact, all the stuff from the hood just got crushed into the space where people's legs used to be.

Beside the fact that if they're true zombies, they're dead -there is no "cure" for that. It might make sense to try to cure 28 Days Later type "zombies", if you define them as zombies at all, but most zombie movies feature the dead kind.
there already are in most movies... the whole "we can cure them!" theme. nobody ever discusses the possibility of simply killing all of the infected. administering a bullet is alot easier than administering an injection.
