I believe you (along with many commentators) assume that my primary mode of transport is driving, since nowhere in my comment I refer to drivers. I was commenting on sharing sidewalks and streets with bikers as a pedestrian. There were many times for me when, at a stop sign, a car stops, I start to cross, and nearly run into a biker who ignored the sign, this is what I was referring to in teh part about stop signs.
You both make some valid points; I don't use 'bias' to imply you are wrong. Rather, bias affects the process by which you examine and evaluate your points.
