Yes but those problems you just listed, like exposure, would apply to the zombies as well.
I also think you're underestimating our adaptability. Some of the outliers in terms of fitness and health would be screwed, but I think most adults would be fine. Also, a zombie apocalpyse scenerio always seems to assume that the military some how ceases to exist. I really doubt that every military in the entire world would just stop functioning. I think you would see fortifications made by the military and numerous airstrips set up and secured to which their would be flights to and from these fortified colonies.
So in my mind, the only challenge for survivors would be getting to one of these airstrips. If you set them up near a calm river (one without any sort of waterfalls or rapids that "sneak" up on you), it would be even easier for people to make it and avoid zombies.
Pshh. I say bring it on!
(P.S. I think the outbreak would be under control far before fuel reserves run out)
