Hey... That's photic profiling! Why is it always about the black ice? Huh?

..

..

Actually this article is pretty amusing:

.

'...

The system is capable of determining the iciness of a road on the basis of a drive of a few kilometres.

The information is then passed on to the driver, before changes in road conditions are noticed...'

.

Requiring a couple kilometers to determine iciness suggests the info wouldn't be very timely...but then it does say it passes the information on before the conditions are noticed... by whom?

.

It the road conditions create difficulty for a driver to stay on the road, this will become obvious to the the driver and anyone behind in a much shorter distance than a couple kilometers.

GA!

We can also use the visual clue of cars and trucks in the ditch as an indication of slippery road...

Joke aside, as the cars become more automated and include various traction control, people loose the feel of the road and cannot tell that it is slippery. Drivers, in general, are not aware of the difficult conditions and drive like in the summer.

Should we add highway automation to compensate for their flaws (at the expense of everybody else) or force them to take lessons on winter driving like it is done in some northern European countries?
