We were driving to Ocean Beach in San Diego when this car sped past us, cutting us off. A few moments later this motorcycle passed us as we approached the now sitting car. He kicked the mirror and as a result crashed into the curb. The mirror flipped and I could see it was broken as he passed me chasing the biker. I followed them for a few blocks, they both pulled into a parking lot for a second and then sped out. I lost them at that point. I never heard or saw anything more of the incident. More
