Dickhead driving in the left/passing lane, doesn't yield to faster traffic (meaning me)

after a more than reasonable amount of time, faster traffic is then forced to pass on the right

but then....

butthurt passive aggressive dickhead in the left lane now decides it's time to hit the gas and floor it, which creates a dangerous, awkward situation trying to get ahead of him as he's gunning it or abandon and pull in again behind him (at which point they start to slow down again).
