I know this is such typical anxiety thinking but I was driving earlier and doing 58 km/h in a 50 zone. This truck behind me obviously felt I wasn't driving fast enough through a residential neighbourhood (speed limit is 50 km/h) and sped up really fast, drove super close to my car and passed around me, naturally I held down my horn. He gives me the finger, several times. I continue driving behind him, as I was headed the same way. He changes lanes to get behind me, which sort of freaked me out, I was expected him to do something, but then he changed lanes again and started speeding and clapping his hands in the air. This guy obviously had some issues. When he changed lanes to get behind me, do you think he could have taken down my license plate? Can he do anything with that? Could he find out where I live? This really freaked me out and I've been thinking about it way too much ever since.
