> They have absolutely no positive value. It was explained to me when learning that they are a "Hey, I'm here" button. They can be usefully deployed when someone is, for instance, reversing towards your vehicle and apparently doesn't see you. I think that's a good use for them. They are not an anger button, or a let me through button. (in response to the below, as I am rate limited: Well, you can't fix stupid... But you can help along someone who's bit tired and forgot to look and "oh shit someone's just beeped me aaaaaaaaa I need more coffee". I've been on both sides of that and have yet to actually reverse into anyone else's vehicle)
