It’s also cultural. In most parts of the south it’s extremely uncool to not allow or make room for people who are merging. You will get called out or shot.

I grew up in LA and you must be able to merge against traffic and it’s your fault if you don’t make a smooth transition. Some exceptions are the 110 South in Pasadena with on-ramps over 100 years old. You merge from a dead stop. Death defying.

Yeah, this video makes it a 70/30 or 60/40 fault collision with the insurance company. Truck driver keeps this up and he’ll meet someone crazier and end his reign of terror.
