Using a phone or headphones while riding a bike is idiotic, but for these: > running stop signs, right turn on red without stopping, turning without signalling, running red lights It's important to understand a few things: a) A person on a bike is 1000x more vulnerable than a person in a car, and will definitely lose (physically, legally) if they misjudge the situation and end up getting struck. b) A person on a bike has way better situational awareness than a person in a car— they have a higher vantage point, and a very wide field of view. They're extremely well equipped to judge distances and speeds and to catch things in their peripheral vision. c) A person on a bike often faces obstacles you wouldn't be familiar with as a driver. For example, a red light that can only be changed by triggering the in-pavement car sensor or riding up on the sidewalk to push the beg button. I have such a light on my commute, and I feel that it's safe for me to look both ways and proceed when it's clear (treating the red light as a stop sign). You may disagree on this choice and call me a scofflaw cyclist, but at the end of the day I'm still basically just endangering myself. When drivers whip around a RTOR with their head hanging out the window looking at the traffic they're trying to merge with, they're endangering anyone who might step out to cross the road. All that said, if my local PD committed to broad and consistent enforcement of minor traffic violations, I would absolutely get on board and either commit to riding/walking up on the sidewalk to use the beg button or choosing a route that avoids that intersection. But as it is, they don't have any interest in enforcing any of it, so I think it's reasonable and non-hypocritical for me to make a choice that slightly improves my commute and endangers only me to a degree that I am comfortable with.
