@Jake_Vig may I ask broadly what part of the world you are from? I'm from California, and something I am aware of every time I've been on the East Coast is that letting people merge is not part of the driving culture back there. In SoCal where I grew up, if someone needed to merge into your lane you made a hole for them so they didn't end up causing a traffic jam.
@antares @Jake_Vig I'm in Minnesota, hotbed of the passive-aggressive. On a vacation, I drove a lot, mainly between LA and Anaheim. Best drivers ever. I was amazed, and it was fabulous.
