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.
But driving rules are not precise. For example, when doing a lane change, how much space should you have in the lane you are entering? It’s entirely up to us to judge.
So obviously don’t drive on the wrong side of the road whenever you feel like it, but if you for example want to squeeze into a lane of stopped cars (while your lane is also stopped), I don’t see the issue
in my state the driver manual specially states to change lanes with enough space that you can see both in your rear view mirror both headlights of the car your getting in front of
