Drivers are supposed to use horns for emergency signalling such as imminent collision. I always thought it was a failing not to include a bell or something for non-emergency signalling.
There is the problem of escalation, where people might simply ignore the bell, but its availability as an alternative to horn would clarify horn use is an expression of aggression, and willful contribution to noise pollution.
That said, I still think autonomous cars can’t come too soon, even if we should be looking to vastly reduce car traffic with public transit and urban archipelagos.
