In some US states rolling stops for bikes have been legalized as "Idaho stops".
I have used a bike as my primary transportation for 15 years. The majority of rides are in traffic - there's very little dedicated bike infrastructure (painted sharrows or gutters don't count)
Trust me when I say, in the US, an intersection is the most dangerous place to be. You are a sitting duck if you aren't moving when clear.
A lot of drivers straight up don't pay attention at lights, due to phones or spacing out, and don't give you space when coming up behind you. Mix in right-on-reds, unprotected left turns, and the general drivers failure to negotiate turns - if it's clear I'm going. It's also safer for me to stay at a relatively consistent speed for predictable passing than accelerating in mixed traffic with very different acceleration curves.
