****  Ever have a bug fly into one eye, or a piece of dust? Or for that
matter just close one eye while driving. What I am saying is that having
that ability, I definitely make use of it in driving skills.

*****  If one does *not* have stereopsis functionality, that is a
significant amount of less information available to the driver. That makes
it quite similar to simply not paying attention, which is what can happen
after drinking too. I was equating the relative lack of information which
ultimately is the real cause of many accidents. On some occasions it's drink
that can cause inattention. Other times it's the cell phone, kids fighting,
bees buzzing, well you get the idea...

***** I tried Pulfrich briefly and decided it works a lot better with a 2D
source and fewer side distractions. Though I figured that fully stereoscopic
material could be presented against a background of Pulfrich for quite an
interesting mix. However you need a cross between LCS goggles and switchable
Pulfrich shaders. 

Mostly I watched stereopsis in action, motion parallax, perspective changes
with distance and exercised the ability to judge distances and rates of
travel between my car and the other vehicles on the road. Passing Winnebagos
on the coastal route is a very 3D experience.

*****  Are you suggesting you'd be happy driving with a patch over one eye
for extended periods of time? How about Dr. T the Greek pirate at the next
halloween party? ;-)
