I had it happen too many times that, for instance, at a 4 way stop - one driver would try to wave me on, then get tired of waiting on me to get back on my bike and go and proceed through the intersection swerving around me in some fashion, or sometimes same situation another driver from another direction is tired of waiting on anybody at all and proceeds into the intersection regardless of right of way. Anymore, when I get to a 4 way stop, I put my foot down and don’t even make to look like I’m about to move until I’m satisfied that it’s my actual turn. I sometimes even wait until nobody else is creeping into the intersection. I’m sure it pisses off people behind me sometimes. I’m not dying getting tangled up with a driver in an intersection. Not by my choice anyway. I just act like I can’t see them waving me through. Most of the time I honestly can’t. Sometimes I’ll check my watch or take a drink. That usually gets them moving.
