I've been driving and flying for 50 years now, the roads and skyways have changed significantly sense then, the biggest change for me has been my reaction time.
Over the years I have learned to plan my approach to my destination with greater diligence. When in traffic I purposely calm myself down and watch those around me for traits in the behavior so I can anticipate their next move. I continually scan my area and watch what is happening way ahead of my vehicle, I have never been in any kind of accident.
For me it's all about my brain and reaction time, which has slowed down significantly over the last 50 years but still is better than most. When my reaction time slows to a point where I notice I'm endangering others, I'm done!
