In my day to day driving I do a lot of things to protect me from negligent, irresponsible, and dangerous drivers. For instance, I have to brake abruptly when someone changes into my lane with no warning, no signal, and when there is not a safe distance between us. Or when I have to swerve or stop when people turn into the wrong lane (the lane in which I am turning into). Is there anything that I am able to do to report these drivers in a way that might get the problem taken care of? I know that calling 911 is probably not the best idea, and reporting it to the police might not accomplish anything because it's only my word to go on.
I had thought about setting up a camera on my dash, but a friend told me that that was illegal because it's an invasion of privacy.
What are my options? Is there something I can do, or do I just have to deal with it?
