It's getting more common here. Not just the highways but local road where bikes split to get to the front of a que at red light.

One sport bike came a few inches from my bumper on the i25 to i70 ramp weaving between lanes with a few others. I didn't break to allow a larger gap pinning those following him in thier lane. I could see thier irritation being held up.

I am also a driver who doesn't center my car in the lane to stay out of the ruts and cracks. Most cars don't feel the ruts but wider sticky tires makes it feel like a slot car track. Also allows to see further up past the car in front of me. Had a few bike run up on me and getting stuck flipping me off and trying to wave me over. I just ignore them by noth responding. And this is at the covid 15+mph over limit normal.
