WOW!!!!!!! Glad you were able to ride the line!
Like you, whenever I ride I'm always trying to predict what the cagers are going to do. I keep my finger on the V Strom 'Passing Light' trigger so that whenever a driver is intersecting my path, I will pull the Passing Light trigger and hold it steady. So far that has seemed to work well to enable the 'blind driver' see me and not pull out in front of me.
I avoid riding in the dark these days so I never thought of using the high beam trigger for improved visiblity. Good idea. I'm a big believer in the old "watch the front wheel for movement" mantra.
I will sometimes start weaving when approaching an intersecting driver: a slight weave if there's a car behind me, a lot of weave if there isn't.
It's not a popular opinion among my fellow riders, but I ride with the philosophy that if I get into an accident with another vehicle, it's nobody's fault but my own.
Not saying I'd admit fault if it wasn't mine in the case of an actual accident, but I don't depend on other drivers to do what they're supposed to do. I consider it my job alone to anticipate and avoid collisions with other vehicles.
Closest run-in I've had lately was a school bus that didn't see me and pulled through an intersection from a stop sign right in front of me on a busy, narrow one-way street with car parking on either side of the street. Not only did it pull in front of me, it stopped right in the middle of the intersection when something happened with the vehicle it was following.
Let me tell you, a school bus can move faster than you think and will completely block an entire street leaving you nowhere else to go. It was like The Road Warrior
where they used an old bus as a gate to their compound. All it needed was some steel plates welded to the sides and a guy standing on top sporting a mohawk, eyeliner and chaps with his ass hanging out to complete the effect.
Fortunately, I strictly adhere to the posted speed limit on that street as there are lots of kids getting into those parked cars on both sides so the brakes, the only option I had, were enough to avoid a collision. I'll never look at a school bus the same again........
