Nah. When you look at the groups that employ body/dash cams (Police, Russian drivers, …) what they have in common is that they are involved in activities that have a high likelyhood to get you involved in altercations and it can be really important to have the incident on camera from the first second on. This simply doesn’t hold true for most people - not to a degree that warrants attaching a permanent surveillance device to your body when you already have an easily accessible on demand camera with you.
