Not a bad reminder.
When I was younger I was driving near the river one night on the way home and tested the breaks to find it was very slippery. I slowed way down. A car came up rapidly behind me, went to pass, and just a few feet in front of my car they lost it and started skidding sideways down the road. I could see the front wheel on the other car actually turning slowly backwards as it skidded. Because I was still going straight and in control I was able to break and the other car pulled away from me while sliding sideways! They hit the shoulder of the road and spun all the way around and into the ditch. I stopped to help and a group of teenage boys tumbled out of their car apologizing. We did a little digging and they pushed themselves out and drove away at a much reduced speed. They were in front of me now and a few miles further down the road when we were not near the river I tested the breaks again and found the pavement was now dry. I ended up passing them on the way home.
