Smart GPS already exists but driver's need to maintain situational awareness and exercise caution.
On the portion of I81 in West Virginia there are lighted programmable billboards which can flash warnings 9f conditions ahead. They get used almost daily.
Most important in conditions of low visibility is to turn on your flashers and SLOW DOWN. If possible pull far off on the shoulder, leaving your flashers on and EXIT THE VEHICLE. If you have CB, ham or GMRS radio transmit a warning and call 911.
I avoid I81 when possible, as these kinds of cluster foxtrot happen all the time.
