I think one has to use a little common sence when you approach this topic. Yes, in an ideal world, one doesn't move the coach unless everyone is belted in. HOWEVER, there are times when unbelting is not a problem. I try not to have my wife go for munchies and beverages while moving, but sometimes it is "necessary". You don't have the errand runner move while the coach is on curves or questionable traffic, but as long as you are going in a level, straight manner, with no acceleration or deceleration forseen, there isn't any problem in releasing the latch and using a little freedom. When traveling with 8 in the coach, I permitted one of the three occupants of the couch to go lay on the bed. Safe? Well if I wanted to be perfectly safe, I wouldn't have gotten onto the interstate in the first place!
