Good advice, but a long list to remember. My Mantra for riding is, was, and always will be just two bits of wisdom:
1. Never hit anything with your bike.
2. Keep in mind at all times that every other vehicle on the road is there with the expressed purpose of trying to kill you.
I agree that you cannot remember all of the bits and pieces of advice given for safe riding here, or anywhere all the time. Your two part mantra sumarizes it all, and serves you, with 30+ years riding experience, very well by your own account.
My purpose in posting these safety tips is to help the many newcomers to riding to be able to read and then visualize themselves applying the individual principle being highlighted, while sitting at home. Practice it over in your mind, just like doing a preride inspection, so that in time it becomes an automatic reflex action, with little or no conscious thought to respond.
KM, I believe that is the point you have attained in your riding skills. You do not have to think about individual responses to traffic moving around you. Your "brain speed", honed by many years of experience, allows you to see, decide on a couse of action, and execute it in a fraction of the time it would take me or many other new riders.
Let me illustrate a similar idea with an example from my own life. I have been driving for over 50 of my near 57 years. I slide behind the wheel, insert the key, start the car, put on my seatbelt, check/adjust the mirrors, engage the brake, shift into gear, shoulder check and smoothly pull out in more or less one fluid movement. It takes me less time to do it than to describe it.
One of my sons-in-law, at age 27, had hardly ever driven when he married my oldest daughter. She did most of the driving for the first several years they were married. He came with me to bring the car home from the service station at Christmas time about 10 years ago. When we were ready to go, I stood waiting to open the door (it was about -30*C outside, so I wanted to open and close the door as quickly as possible for the comfort of the other mechanics in the shop.) He got in and started the car, so I opened the door. He then fiddled around for at least a couple of minutes adjusting mirrors, putting on the seatbelt, yada, yada, yada, until he finally pulled out. I could have pulled out and back in again 4 or 5 times by the time he finally got out so I could close the door.
I was losing patience with him because he had to make each move deliberately, and think about it, where for me it was all an almost automatic action.
So to all you new riders like me, read all you can at home and think about how it applies to you, do some "chair riding" and practice just as though you are riding the bike.
Then later, on every ride you make, pick one area of your riding you want to improve, and critique yourself or have an experienced riding buddy do it for you if possible.
