Occasionally when you’re driving, you’ll make a mistake and perhaps need to adjust and it can create some awkward situations. Like today, my dad ended up in the wrong lane to go straight instead of turn at a light. He had to cut in line to make sure we could go the right way. It’d be nice if we could communicate “sorry, I screwed up. Excuse me. I just need to slip in there.”
Right now all we have for inter car communication is the horn, which has kind of an aggressive implication to it. This is for trying to de-escalate potential road rage.
It is all prescribed in the rules, they are precise. Even if they aren’t precise, the judiciary decides what the rules mean, law has no ambiguity, and if there is, the ambiguity is resolved by a judge.
Cutting in line is not against the law though. It’s just considered rude, which is why OP wants a “sorry” honk
There is a culture problem if a legal safe move is considered rude.
Traffic is giving and taking responsibly.
Judges disagree all the time and then it gets decided by the highest appellate court, potentially with a split vote.
The laws are not perfect by any means.
I didn’t say they are perfect, but they are in the end absolute.
They can change over time, but at any moment there will be an absolute decision.
