I disagree, cossack. I acknowledge that you have experience and training in fitting multiple aircraft onto runways, but I'm the one flying the airplane. As pilot in command the final responsibility for the safety of my flight rests with me. It's my right to say "unable" if you ask me to do anything I judge unsafe. If you don't agree with my judgement, it's your right to mutter "stupid pilot" and let five departures from the other taxiway off ahead of me.
