I went back and read the op's original question. His question was: Are we breaking the law in a pace line by not giving the vehicle in front of us; aka the lead bike; enough space cushion. As far as motor vehicles are concerned, tailgating is considered aggressive driving that couldbe interpreted as reckless driving. So the op has a good point. In a paceline cyclists are tailgating each other therefore braking the law by driving recklessly. The Texas drivers handbook says cyclists are to obey the same laws as motor vehicles. So to interpret the law literally... We are brakeing the law in a paceline by not giving enough space cushion to the other vehicles on the roadway. My 2 cents...
