Good point.  I was under the assumption that there was more to the
argument than just getting up to speed quickly that perhaps another
congestion control strategy might help (e.g. equation based).  Your
analogy points out danger of 'network whiplash' when those flows ramp up
too quickly and ram into the car in front, causing severe oscillation
and short bursts of congestion.  Perhaps you need to give those
complaining about TCP's behavior a seminar in the end2end argument?  :-)
