In my view, lane-splitters are daring me to not hit them. Since the eyes in the back of my head don’t work as well as they used to, it becomes their problem, not mine. I check out the lane next to me, not the line next to me.
BTW, my son, who rides a motorcycle, is not stupid enough to lane-split.
I wish that attitude was limited to you, but unfortunately, it's common.
The best argument against the practice is drivers like you.
