That is a good thing. I thought about getting a dash camera but I never did. But now, people will film you for doing anything. Taking a whiz. Taking a dump on a Police car. Getting the tar beat out of you. Your vehicle getting hit by a freight train. Or just walking down the street. You name it and do it. They will film it. And why not? It gives them something to do.
As I explained to a guy years ago while videoing him while his car stereo was REALLY LOUD and he told me to stop filming him: you have zero expectation of privacy when in a public area...and lets call the cops so they can verify that for you (which they will). Don’t want to be recorded? Stay at home.
