I'm also getting a bit arrogant, I never greet.

But I'll greet back.
Although yesterday morning I was filtering heavy traffic on William Nichols, and a there was another guy on a bike in front of me who was 'filterering' at almost the same speed as the cars around him. I was fuming behind revving like an asshole. Then when I arrived at the robot next to him, I just ignored him. That was a Monday morning, so I still have an excuse to be arrogant...
