Rationally

You realize that your brother has a point. You watched old zombie movies back as a kid. You enjoyed watching the recent zombie TV shows with Will and Amber. It was hell to pay when your mom came home one day to the three of you watching them, but it was worth it. Especially now if it may actually help you stay alive. You know that you have to stick together. The groups that can't agree with each other are always the first to get eaten or get killed.

You put on your best fake smile and tell him "You're tired Will you should maybe get some sleep. We can take turns at the wheel so we are all well rested. It's going to be quite a few hours drive still."

At your fake smile much of the concern disappeared off Wills face. "That's my sister. We can take anything life throws at us. Do you want to take the wheel or should we let Amber keep driving?"

Amber pipped up from the front. "I'm good to go for hours! Get some sleep!"
