When driving, i feign changing lanes w/o looking to merge @ last min.
When you've driven a while, you may have had occasional situations when you forgot to look before changing lanes and there was another car there. As soon as you started to veer into the lane, you get honked at if not in an accident in the worst case scenario.
Sometimes, the driver in the other lane will just reluctantly let you in anyways even though you didn't have the right of way.
So now, I take advantage of the latter type of driver, especially when trying to merge at the last minute if my lane is going fast and the lane I want to enter is going slowly.
I'll signal to go into that lane and start moving towards that lane as if I forgot to look first. Just before I cross into the lane border, I suddenly backtrack as if I suddenly realized there's a car in that lane.
About 50% of the time, someone will let me in, thinking I'm a careless driver who didn't bother to check. Another 20% of the time, I get honked at but I don't care as I still stayed in my lane.
The intention of this move is simple: it's to intimidate the people in the other lane into letting me into merging.
