Why are random people taking pictures of me in my Tesla?

For example: I'm driving on autopilot. Basically, my car drives for me on the freeway... so, I am glancing at a book. Meanwhile, some asshole is busy taking pictures and recording me. Today it happened again. I am rummaging through my purse. As the car is driving for me. I pull up a credit card and catch another person taking pictures and/or recording me. My concern is for my identity with my credit card... but, can anyone tell me why people are doing this? Its twice this week. Also, these cars do well and are perfectly safe to drive themselves. I dont see a reason for anyone taking pictures or videos of my activities in my car while it is driving. These cars have a million safety features and are safer than the people who drive themselves.
