Missing all the ‘before’ portion of the video.
The best term I ever heard in a traffic school I attended (totally voluntarily, of course! 
) was ‘conditional priorities’. There is no ‘right of way’; there are ‘conditional priorities’. They constantly shift, depending on what is going on.
So I’d like to see the part at the beginning, where the white car could have totally and reasonably let that car in (especially if it was as simple “you then you then you then you” merge and he hadn’t yielded to…I don’t know…just like ‘one’ car). Does the video at the beginning show the white car hugging the car in front, while everyone is going like…10…refusing to let one, little car in front, lest he lose his precious 25 extra ft between his life being an overwhelming success and a complete disaster?
Thinking you have a right to anything on the road leads to all sorts of problems. Conditional priorities. Plus, “don’t be a dick” is always helpful.
