You never been on the Mass Pike in January!
I used to drive 58 miles each way, and stopped taking the MP, since the
back roads were cleared better and sooner!!
I'll admit I was generalizing, but I still assert that the system
would be more useful on secondary roads than on the major ones. At
least that has been my experience driving in Illinois, Indiana,
Connecticut, PA, MD, DC, NC, and northern VA.
South Eastern VA is messed up though. They plow secondary roads, but
just salt the highway. In '96 I was driving after a storm there and
had to slow down to about 20 on the empty four lane highway going
through Newport News in order to change lanes. The ruts of sludge were
so deep that they would spin your car once you had one car in the rut
and one out. I spun three times that day while never going over 30. So
you have a point, but I still think the system has such limited use
that it would be more practical for the cameras to arm a flashing
light on the side of the road by a sign that reads,"ice ahead." That
way everyone can see it, and the government spends money to put it in
places where it is needed versus Nissan building an entire system on a
car with cameras and associated operating costs that would only be
used part of the time.
