You don’t keep honking, or even start honking, at somebody whose trunk is open. They’ll never figure it out.
An open trunk means an unsecured load, and an unsecured load is a safety problem. But yeah, a honk alone isn’t enough to communicate about it.
Trouble is, once someone forms the hypothesis “this is someone raging at me” they’re going to have a hard time updating to “this is someone trying to help me”.
Dude should maybe have turned down his music if he’s sincerely trying to communicate to another driver. In slow highway traffic it’s totally possible to holler “Trunk’s open!” and be heard … but not over chunky bass.
It often seems to me that the hard problem of consciousness is equivalent to “Why are people dissatisfied with easy explanations of consciousness?”
