I agree with Bob B about sensible upgrades over original to improve your chances of seeing and being seen. I also agree with Keith True about the “armchair experts” who expound, often vociferously and adamantly, without investment. Here in California motorcycles are allowed to “lane share”, which means that a motorcycle can pass between two lanes of traffic if there is physical room even if not a full open lane. Very useful in beep-and-creep traffic, and quite reasonable if done carefully and respectfully. I cannot count the number of people who used to tell me how stupid I was to do this - none of them riders themselves. (I don’t ride any more, but for different reasons than traffic safety).
And Brent - to your point, it seems to me that a good portion of the cars I’ve seen on club tours that end up with roadside seminars were previously restored (maybe back in the early heydays of this hobby) but maybe not a whole lot of attention since then. We are spoiled by modern cars being so reliable. Hell, you don’t even need to check your tire pressure any more, just wait for an idiot light! I remember my dad had a first weekend of the month routine that included tire pressure, battery water, oil, transmission, air filter, rear end, lights, belts, hoses, and likely more. Not to mention things that were mileage-driven like oil change, lube and valve adjustment. I know I am guilty of pretty much ignoring my own modern cars, maybe because they are not much fun to work on (how excited can you get changing oil on a Prius?) But I do try to keep up with the Model As.
