On the freezing cold and with zombies around? It makes sense im theory but that might as well be risking it all on nothing... Getting sick is just the top of the iceberg, imagine the frostbite or your skin getting stuck on an ice surface, that'd be painful and zombies could easily get to you, ouch ouch Σ(  ̄□ ̄||)
Just drive next to the truck, get on top of the car, get on top of the truck, jump over to the roof of the building thingies, then jump over the wall.
