Multiple incidents happened today, but this one really stood out. I was driving on the right lane of a 4-lane section on the 210East freeway, and this white Nissan Altima comes racing up behind me, and apparently amazed that I didn't bow out of his way in horror, decided to give my car a rectal microscopy. Unfazed, I maintained my leisurely 55, as there were no near exits and almost no traffic to prevent him from going on to any of the 3 other available lanes. So he sticks behind me for about a mile and then this merging lane comes up and he tries PASSING ME ON THE RIGHT! This is a common offense, but there was hardly any space for him to safely do so. I have had this happen to me many times, but there was such a small amount of space that I really wasn't going to let him have his way this time. So I sped up and intentionally blocked his way, as I really wasn't going to tolerate this reckless conduct. Instead of just passing me on the left like normal human beings with an IQ above 75, he just glues himself behind me again, headers on. Then an exit shows up, and he roars down it, only to break at a stop sign. I would have taken a picture, but I was laughing too much at the level of idiocy some drivers seem to exhibit.
