So basically my family and I are in LA on vacation. We rented a car to get around. One evening, my father was stopped at a light. The light turned green and he started advancing. All of a sudden a guy on a bike tries to cross the road and my dad hit his back wheel. We weren't going very fast and the guy fell off. My dad pulls over and asks if he's ok. The guy starts cussing and yelling. His friends came up and two of them started arguing with my parents. Basically the kid said we should just give him money or he would get us deported (we're American citizens) and basically being an all around jerk. My dad got witnesses that agreed he ran into the street. I know the law is you have to respect pedestrians and cyclists but basically the guy came out of nowhere and we didn't have time to stop. Eventually we just left. I'm just wondering what could happen and what should we have done to improve the situation. My parents wanted to call the police but the guy and his friends told us to just f**cking leave. I'm hoping to get some insight here as everyone seems to be pretty informed about the laws here.
