Besides radar I think there's a lot of potential for automated systems to help drivers cope with snow & ice. For example a sensor scanning the road able to warn the driver of black ice, or at least inform the driver that they may be seeing rain on their windshield but it's freezing on the ground. Maybe speed controls based on real time weather conditions. No one should be going over 40MPH on any road in the snow. How about using cars as a way to measure road safety? Monitor the road conditions and the cars traction and report this information to the DOT so a plow/sander can be dispatched to particularly bad areas.
