While walking I've almost been hit by cyclists performing "Idaho stops". It was one of the big things that turned me against the movement to promote cycling as a form of transportation/commuting.
Are you also against using cars for commuting, since they kill pedestrians all the time?
In reality bicycles have extremely good maneuverability and visibility, combined with lower speeds and a small hitbox. As someone who frequently walks and cycles I feel that on foot, something might "feel" like a near miss when the rider was in fact in complete control the entire time or was able to avert a crash due to all the inherent advantages bikes have for reacting quickly and decisively.
No noise pollution. No air pollution. Requires only a fraction of the amount of public space cars do for mobility and storage. Massively improved visibility of surroundings w/r/t cars. Smaller hitbox with lower weights and lower speeds, translating into a massively reduced momentum differential in a collision, plus way more runway and maneuverability for avoiding the collision to start with.
The Idaho Stop improves safety for cyclists because maintaining speed and visibility through a junction while slowing down cars mitigates the risk of a right hook. Telling everyone that they should categorically expect this behavior and that it is legal improves safety for everyone. I as a pedestrian and cyclist in DC expect Idaho stops from other bicycle users and act accordingly, the same way I expect pedestrians to jaywalk anywhere and anytime they want and act accordingly, and it's all quite safe.
