Thought lane splitting is only done at a red light
I need to be more educated.
Hope I don't get off topic, I have been able to avoid accidents so-far, But yes, stupidity is a factor. Ignorance may be another problem.
As for the biker in your post having room on the right to pass, it's illegal for vehicles to be in the left lane unless passing.
Rider/driver education sucks big time, speeding to catch the last 0.0001 seconds of a yellow light is illegal yet students are taught to break the law ( I've seen it ). People will stop on the freeway in the left lane to get to the exit that's 5 lanes to the right, ( again why were they in the left lane?)
Cars turning right on red is fine, but for Pete's sake come to a STOP like the handbook has printed in many languages.
Cagers and bikers changing lanes at freeway speeds is a good one, seen certain bikers just use a hand signal, twist the throttle and go without actually looking to make sure it's safe, the loud pipe will save then. Cagers will begin to ride the lines, bouncing off of them, then they will gradually be on the line slowly entering (my) the next lane, THAT'S when a signal is used, and maybe a slight twist of the head can be observed. My Stebel has had them move back fast
Still do not know why they did not see my Brights, Hi-Viz Jacket, Hi-Viz Helmet
