This is why I am disgusted with the foreigners, illegals in this country. They want take responsibility for their actions. I live in Florida, had a delivery driver for me bump someone at a red light back in the early 90's, all because someone ran the red light and the vehicle in front her went forward then made a sudden stop to keep from being creamed. My driver put a small dent in her bumper. Since it was just 2 blocks from us I went and and oversaw that insurance and license numbers where exchanged and also told the victim that we would pay the cost of the repair to keep our insurance rates from going up. She was completely happy and I apologized for the inconvenience that this may caused her, and she replied, it was neither of there faults because the red light runner is what started it all.
Now her husband says, you need to get a police report and believe or not, they charged our driver with the accident and also charged her with leaving the scene of an accident. I had a discussion with the police officer and told him what happened and that we exchanged insurance info and all and that our company was going to pay the dent to be fixed. But since her husband started this with police department they had to follow through. Not only that, if an accident is under $500 the police did not to be called to a fender bender.
Now I noticed you live in CA, I guess your laws or very liberal. But, you can ask for the a police report and also they could charge her with leaving the scene. Maybe you can get justice this way.
