Am I in the wrong? Or is this standard?

[Illusionist]

On my way home on the highway I was doing 75MPH in the HOV lane ( around 7:30PM not much traffic ) The speed limit is 65 MPH.

There is a car in front of me about 3 car lenghts, So i'm keeping a standard distance for doing 75 MPH.

SUV comes up behind me some what quick and starts to flash his high beams. (trying to get me to speed up or switch lanes)

This is a big pet-peeve(sp?) of mine. I continue going 75 MPH cause if i go any faster i'll be tailing the guy in front of me.

The SUV starts to get Angrier and starts to flash em more, then decides to just leave them on.

After a good 15 seconds fo him leaving them on and tailing me, I do the following

1. Speed up 5-10 MPH
2. Slam my breaks
3. Floor it.

Me slamming my breaks scares the [censored] out of the guy causing him to have to pull over into the emergency lane, because he was scared he was going to hit me.

Once he gets back into the lane and behind me again he does the same thing again, So i get out of the HOV lane to let him pass me.

I get behind him and turn my high beams on(standard?)

This makes him slow down to 30mph(not hitting breaks hard) i turn the high beams off he speeds up back to normal. Once he's doing 65 i turn my high beams on again and he starts slowing down to 20-30mph

I get out of the HOV lane, do a sinster laugh and take my exit.

Was I in the wrong?
