DRJAD,
Fully agree with you. I go my PPL in June, got about 70 hours now. Running through the flight while driving home was the time when I learned the most. When you have got time to think about it, and go through it in you mind then the things that you got wrong or didn’t do as you should, you remember for next time. Worked wonders for me!
My instructor could never stress enough about looking out of the window and making yourself be seen. Also listening to the radio to build up a mental picture about what the other traffic is doing. Then you can react, if you hear that someone is going to be over the VRP where you are going, etc.
Lessons that a lot of people could use in life on the ground, as well as in the air.
Happy flying!
