On my fishing trip this evening two more things came to my mind and as I didn´t find it posted here I´ll do now.
Long shadows in your driving direction indicate a serious thread. Act as if you were invisible to other drivers as you may well be just that. It´s an unsymmetric low vision scenario. The sun in your back conceals your approach to drivers in front of you while you can see them clearly. That makes sunset or sunrise more dangerous than rain or fog. That fact is not always taught properly.
When started riding motorcycle I attached a hand counter to my handle bars. Every time I made a mistake I hit the counter. That has two effects. For one thing you admit to yourself that you did something you should not do. And to a lesser degree you get a count of your mistakes. The count can go up even when the driving gets better. I got more critical and started counting things I did not even notice when I started counting. The counter is also a constant reminder that I make mistakes too. It helps putting the "inconvenience" of safety margins in the proper perspective.
