The alternate beginning to 28 Days Later, or a very bloody Every Which Way But Loose.
Before there was the Tokyo Drift, there was the boring drift; getting close to a big rig and letting the airflow behind it pull your car without burning gas. Trouble is, truckers hate that (and it's super dangerous if they stop short). Even more than truckers, violent monkeys and Great Apes really don't like that, and they have the strength to do to you what truckers do to a bowl of grits and an easy lady at a roadside Waffle House at 2 a.m. Or maybe the truck is actually filled with featherbed mattresses. We're sure as hell not going to find out.
