It's nothing too new that you can buy an SUV that comes with anti-rhinoceros protection. I think we can all agree that that's a good thing. But it occurs to me that in every zombie movie, there's a scene where the characters trick out a van or bus with all kinds of anti-zombie gear. So why can't I buy a Range Rover with zombie protection built in? It'd be at least as useful as the rhino accessories-- the chances of being attacked by a rhinoceros at the Twin Oaks Mall are about the same as being attacked by rogue zombies-- and so very much cooler.
