Draw a line, say this is for bicycles, pedestrians and cars have no business here, and bikes have no business being on any other lane as long as these exist.
When bikes have to go through areas where people walk freely, they need to limit their speed to a walking pace.
People should not wear headphones (noise-cancelling or not) when going through traffic as pedestrians. Take them off when crossing!
People should not hear loud music when driving - max is normal speaking voice level. Bike drivers should never hear any music, let alone wearing headphones. Behind-ear speakers on low could be a compromise.
Hey, we just solved 90% of the accidents.
