The unwritten rules of cycling

I watched a small portion of SportsNation and one of the topics of discussion was whether Contador's attack when the chain on Andy Schleck's bike failed. Colin Cowherd said that there was no responsibility for Contador to wait for Schleck. For one thing Colin wouldn't care about cycling if there wasn't Lance Armstrong as a competitor. Since his views are that the unwritten gentlemanly rules of cycling don't matter. I am going to go about writing these unwritten rules that I have picked up from my many years of watching the Tour de France. They are as follows:
1. You have the responsibility to slow down the pace if your major opponent crashes or has a mechanical problem. This rule primarily is related to mountain stages and the ascents.
2. No peeing on crowds when you have to go on mid stage.
3. Crashes are part of the race, but when the entire peloton crashes and takes extraordinary amounts of time to get back on the bike then the peloton has the responsibility to neutralize the race.
There have been two different cases of incidents, crashes or mechanical incidents, that have significantly altered the race. The first was Frank Schleck's crash on the cobblestones of Northern France. His fellow teamates attacked on that section of cobblestones and had no responsibility to wait for Lance Armstrong and Alberto Contador. The other incident was the chain slipping on Andy Schleck's bike on Monday's climb to Port de Bales. In this case Contador should have stopped his attack until Schleck was able to rejoin the group. The key factor is that it seems Contador didn't know his opponent had a problem.
Today's stage was very interesting with the first climb of the Col du Tourmalet. Also we saw Lance Armstrong in a break for the first time since he lost seven minutes in the Alps. He showed glimpses of the old Lance, but he clearly didn't have the strength and stamina to pull away from his breakaway companions. It is sad to see Lance in his swansong Tour suffer from age creeping in on his amazing talent.
