There's another advantage that rarely occurs, but if its raining outside when nature calls, you don't have to exit the TV to use the bathroom.
I got stuck in a huge traffic jam in Colorado a few years ago. The police shut down the expressway in both directions for several hours. I heard later that 3 guys pulled their car into the median, jumped into another car and drove off. When the Police arrived, they popped the trunk and found what appeared to be several pipe bombs. Everything stopped while the bomb squad was called. I could have rented out my bathroom for big bucks that day. No nearby trees to hide behind. Never did find out the outcome.
