You may have seen this technique done while driving around lately. Someone is pulling out from a gas station or shopping mall and you are slowing to a stop. The person leaving the area pulls just slight ahead of you and smiles (optional) and waves at you, thanking you in advance for letting him ahead. If the person sees this and is okay with it, all is good. Most of the time, not so good.
Today a taxi-van pulled out in front of such a driver and when honked at responded with a raised finger, most likely the middle, but I was too far away to confirm. The taxi then stops parallel to the car (in front of it) and waits for traffic to stop so he can make a left turn. The whole time, both drivers are swearing at each other and making rather rude faces.
To avoid this kind of misunderstanding, it would be wise to either retire this communication protocol or redefine the ACK cycle to allow for better transmission and fewer dropped packets… Wait, sorry, that’s network speak.
I dunno why I’m posting this. I just thought it was funny to watch this taxi guy be a total ass. If you are a pre-waver… you suck. 😀
