So, I was driving to work get to this turn where it goes slightly uphill and turns at same time, so of course I hit the gas a little more to get that nice "almost drifting" feeling going, as I make my turn I pass a green 850i.

It looked pretty sweet, then I keep on going my way. It doesn't take long for me to notice that the 850 is driving faster and he gets right behind me and flashes his highs twice.
I look around and see that everything's safe, then (I now can say this) downshift to 3rd and hit it, felt that nice m54 kick in and speeds going up

we're in a 3 lane road and am having fun doing my favorite trick by zig zagging through traffic, and he's playing follow the leader

so we do that for a few minutes and we get to this part where I usually see cops around that time a day, so I slow down and flash my brakes a few times and he passes me.
Here are some pics of it as we approached the next red light
