There was a schematic for an Ice Detector in Popular Electronics when I was in Tech school...in 1979... All that was was a glorified thermometer that hung under the front bumper of the car and would light a bulb or sound an alarm if the temp under the car reached <32 degrees F. |

Volvo had thermometers mounted under their cars in the eighties. No light illuminated. The nissan system is totally different though. It uses cameras stationed on roads to detect ice, then send data to the car. Much more high tech. Seems silly to me though. The sheer number of cameras necessary for this to cover every road would be cost-prohibitive. The first solution that comes to mind for that is to only cover major roads. However, that makes little sense since the major roads are usually treated well enough that ice is not an issue, or it is obvious that it is there, or there is plenty of room. The secondary roads are the places that ice is the real issue, and covering every last one of those is just not realistic. |

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. |
