Fool flashes his high beams and attempts to pass in the middle lane (without signalling of course).
I figure it's a 520i or 520d (that's what most 5-series are here) and decide to give him a lesson. I signal, drop it back in 3rd and floor it. The BMW looks like it's been stuck in mud. I get her to 150ish kph then drop off as we arrive to the next set of lights.
That's when I saw what kind of 5-series I just had smoked :

Driver of course passably annoyed

Oops. Maybe he missed a gear ???
