What you can't see is how this BMW cut off the truck. The BMW was behind me and cut off the truck to merge over. The truck driver had no idea they had sneaked in that tight, as he was already trying to merge over. Then the BMW driver goes on to block someone from merging, I suppose because only he is allowed to cut people off. Then instant Karma. I felt really bad for the truck driver, this will be ruled his fault without knowing all the context. I wasn't able to get in touch with the trucking company or driver.
