Right . . . pretty cool, huh? To my mind the basic issues impacting
implementation of such a system are:

<> Can a system that accomplishes this be developed and implemented while at
the same time preserving many of the GOOD things people like about automobile
travel, i.e. autonomy and anonymity?

<> How can a set of data standards and system protocols be developed?

<> What level of participation is necessary before such a system could be at
least partially implemented? This latter point is especially important,
since the longevity of automobiles has been steadily creeping upward over the
last ten years especially. Many moderately-priced 2001 model cars are so
well built and reliable that we could expect them to still be on the road
well into the 2010s and even 2020s. Given this issue, I would expect that
many of the benefits of such a system will only be achievable if they can be
implemented as a retrofit.

Yes and not much, really (which is true of many cars these days that don't
have completely-enclosed side window frames.) In fact, only two little
plastic clips hold in the windows on my car (and most similar designs). Once
I realized this, I started noticing it on lots of cars. By the nature of
fluid flows, aerodynamics gets to be increasingly important as speed
increases. Thus, for instance, GP cars being able to pull way more than 1
lateral G at even moderate speeds.
