If that's the case, seems like it would be easy to set up some mechanism that would automatically detect that and flash warning lights or something.

Yeah, black ice is just a thin layer of ice that looks like regular road. Maybe wet road.
Thermometer and smart driving is the best we have now, as it can occur in varying conditions. iirc there was a warm front coming in, it rained a little, but the road and ground was cold. Road was clear at my house 10 miles away. We passed over 4 bridges and went through a cloverleaf to get on the interstate just minutes earlier. So frozen road in the morning + a little rain caused it.
A bad one was a warm day that turned cold at night. Making it a little hazy. The bridges cooled down first and froze the condensation. We got sideways on a bridge over diagonal train tracks, hit the dry pavement on the other side and rolled.
Another bad one I took the Jeep to work, and came home on black ice. Had to use 4x4 to get enough traction to push forward. Without it the rear end would break loose and the wind would push me sideways.
Used to have to plan my route when I drove a 2 wheel drive toyota truck in bad weather, because I wouldn't make it up some hills on the interstate.
