I had a similar experience a few months ago. One early morning, I was driving down the Shamal highway, on the left lane, minding the 100 km/h speed limit. A young local in a pickup was tailgating me, flickering his headlights and blowing his horn to give him right of way. Which I did once my right lane was empty.

But apparently, I did not move fast enough for him. He literally tried to hit my car and tried to push me off my lane to hit other cars. 

I lost it, I started chasing him, trying to stop him. Had I succeeded, I would have definitely beaten him, regardless of the consequences. I chased him for 3 more exits, missed my exit and came to work late and enraged.

I would still kick his a$$ if I ever see him again.
