Before covid I would commute daily in London to work filtering (lane splitting) through traffic. You operate on the assumption that they don't see / hear you and you need to anticipate their movements, and be much more switched on. I can almost guarantee no one has ever heard my bike from a car until I've passed by it but it's irrelevant I find as cars try to kill me even when they do see me. Biking is just more dangerous and there comes a point where you are only as safe as you are lucky.
