That’s an American problem. In Europe nearly everyone knows how to drive manually.

At this height there are no trees in the alps. There is mostly rock and ice. And when the ice melts the rocks loose their connection or the melting extending ice/water let them crack.

I could turn this around and say there is no sple way to tell -20°C oder +40°C in F. Who decides that the F Values are the exact points where humans feel uncomfortable when it can be some nearby C ones?
