Well, I rarely P&G in my vehicles, but I do all the time with the bike to work. It's all downhill, why should I bother pedaling when I've reached a peak eff? (given friction and work)
I do find the T de France comment amusing, as I've never seen in any race form, P&G. There isn't time for FE or resting when going the fastest is the goal. I think drafting makes sense there for work reduction.
BTW, what is the d(lurker)/dx? I've been racking the brain and can't figure it out. Awesome to hear about your thermostat experience. I too have found the function of outside temp to inside temp of my home. Fun finding eff in everything.
