We are breathing harder and are not the ones polluting. We deserve to be spared from this harmful imposition. Pollution tends to be highest at stops. Athletes need to come to a stop slowly and cool down or they risk cardiac arrest and other problems. Only the hyper-intolerant or uninformed find a problem.
Cycling helps everyone yet is discouraged.
Give cyclists right of way to help correct this unfairness. Pedestrians aren't required to stop at stop signs, yet can run through them much faster than most bicyclists would. On top of that they can be wearing headphones and much less able to avoid a collission. No one is talking about outlawing pedestrians from treating stop signs as yield signs. One of the reasons is that they give cyclists a head start through red lights, with special zones ahead of motor traffic, and special bicycle-only green lights.
