Wow similar thing happened to me in Malibu. I was driving in the canyons and there was this slow 4x4 with dark tints going down a hill so I began tailgaiting him. I thought he was going to move but then his brakes lights flashed and his tires screeched so I stopped too. Most likely he was pissed off and brake checked me so I eased off a bit and left a bus length in front of us. He then went reaaaaaal slow in a turn and then BAM hit the brakes with his tires screeching. I turned my steering wheel all the way to the right, tried to around him, but he just blocked my way. At this point my adrenaline is pumping and the rational part of my brain just kind of blurred. So I stepped out of my vehicle full of rage to confront him but his tires screeched and he drove off. I chased him all the way to a busy intersection where he was waiting to take a right. I pulled up behind him and again left my vehicle to confront him. It wasn't a him but a her. Yep, a small female teenager who gave me that 'oh fuck what did I just do' look and then proceeded to drive off and merge onto oncoming traffic, almost causing an accident.

Another time in Malibu I was driving on Mulholland late at night after a fun canyon run. I was just enjoying the cruise when I see a vehicle in front of me going pretty damn slow. Sometimes I pass the double yellow line to get ahead of the slow driver in front but this time I opted not to because I wanted to cruise. We were going down hill at some point and I relied on the engine braking to slow down the car. I did not even touch the throttle but I was coming up pretty fast to the car in front. But right before I was about to hit the brakes to slow down, the guy slammed his brakes. I slammed on mine, downshifted, and passed the guy. Now I was in particularly good mood so I decided to let it go, but then the guy crosses over the yellow line and throws a water bottle along with what appeared to be small pieces of candy??? I lost it at this point and went in front of him and slammed on my brakes. He tried swerving around me but I just blocked him over and over again. I rolled down my windows and threw whatever object I could find in my car at him. It turned out to be a tire pressure reader and I heard a loud shattering noise. I looked in my rear view mirror and I saw him dead stopped in the middle of the road. Then some tires screeching as he pulled a fast u-turn. I drove all the way home and totally forgot about my tire pressure reader :(
