I don’t tailgate in the left lane, I just get annoyed by the people blocking it. But I wouldn’t get annoyed if there was some sign the driver was simply waiting for a safe place to move over.
The easiest way for a driver to signal their intention to move over when safe, is if the drive puts on their turn signal, signalling that they are going to move over.
And most of the time, when the driver does this, the people in the next lane make space for them to move over. They know that it’s just a temporary inconvenience to them, since they expect the faster car will move back to the left as soon as the even faster car has passed.
And those in the right lane appreciate the signal, and appreciate the slower car coming over, because the alternative is the really fast car darting into their lane and trying to muscle around the slower car in the left lane, making things unsafe for everybody.
Are you saying that you regularly get stuck in the left lane because people in the next lane refuse to let you in when you signal? Because while I have seen a few drivers who cut you off rather than letting you in, most of the time people are courteous enough to make room for people who signal their intentions.
And I also find that most tailgaters are doing so to “send a signal”, and that they will back off when they see the driver in front of them has activated their right-turn blinker, thus signalling the intent to get out of the way.
Good point about signaling. But it ought to be obvious to the tailgater whether moving over to the right would be a safe thing for his prey to attempt.
