Smart Cars Need Smart Paint
I’m sure you’re aware of the research being done to produce smart cars and trucks that drive themselves. But it may be more complicated than simply designing the sensors for the vehicles. What if there’s snow on the road? Or if the road markings have been worn off, or if it’s raining so hard or so foggy that the sensors can’t see the road?
It turns out that 3M has been working on this for years, first with a smart magnetic paint that vehicle sensors can “see” through the snow, then with smart road signs that vehicles can read to know what’s coming up ahead.
The big problem, as with everything it seems nowadays, is to figure out how to prevent hacking. You’re driving along the highway at 50 mph and the sign tells your car to speed up to 90!
Anyway, some new smart paint developments to keep your eye on.
