I remember an ambulance was right behind me at an intersection. The right turning lane was free but it was right behind me. I got really uncomfortable because I had 0 idea what to do, if I was supposed to basically break the law and go into the intersection on red so that it could get by. After a few seconds, I decide to pull into the right lane but I guess the ambulance driver had the same exact idea at the same exact time and almost read-ended me. So then I get back into the other lane and he goes through the right lane just fine, like he could have the whole time. I'm not blaming anyone btw, maybe he thought the light would change soon or something.
I wanted to get out of the way, but I had no idea what way the ambulance wanted to go. In my mind, if it wanted to go forwards, it just had to get into the right lane and run the red light (which ofc they can do). I think everyone was equally confused because everyone else just sorta froze to let it go by in the right lane.
