Actually the original post that I responded to was the one from billbears to SoldierDad. SoldierDad said everyone should drive 55 and stop wasting gas and billbears told him to mind his own business (*grin*) and that his car did better at 70 than at 55. SoldierDad said, "BS" and GingisK responded with that nonsense about drag. I pinged you on the post because you had responded to GingisK as well.
BTW, my XK has the ZF tranny as well. I am sadly familiar with "the lurch." Thanks for the link, though. I think I'll start annoying the local Jag dealer about it. I thought I would just have to live with it.
Your sad lack of understanding physics does not make it nonsense. Your car has high performance because the engineers who designed it know physics well. For 95% of the cars on the road, my statement is dead on. For the high performance cars, such is not the case. I don't think in terms of the exceptions when making the general case. Since when did misspeaking initial arguments invalidate facts?
You are the one who fails to address the issues. I have asked several questions, and you have failed to answer them. Of course, to answer those questions you would either have to agree with me or expose your ignorance.
