Years ago I was commuting on a cold and snowy March day.
I was driving down a level residential street at twenty miles an hour.
What I did not realize was that there was ice underneath that coating of snow—and all of a sudden I skidded off the road.
My tires were in excellent shape.
I had not touched the accelerator or the brakes.
It is amazing what ice can do.
I remember one night years ago, I saw a pair of headlights well behind me. They were in a normal horizontal orientation. I looked again, and they had gone vertical. The vehicle must have found a ditch.
Another time, I saw a snow day picture of a four-by-four perched on top of a guardrail. Many people think that four wheel drive cancels out the laws of physics. It doesn’t.
