Q: I know some wrestlers that share rental cars think it's disrespectful for passengers to sleep since the driver doesn't have that luxury. But with the schedule (only getting 3-4 hours of sleep per night) most of the boys have, it would seem like the perfect time to catch a quick nap. What is your opinion of passengers sleeping in a shared rental car?

A: There is an unwritten rule that you have to stay awake to help keep the driver awake but some guys do sleep. Most guys will ask the driver if they mind before going to sleep. When Christian Hurricane and I would travel together Christian and I would stay awake and cover the driving and Hurricane would sleep in the back.
