I watched your review. Your text here is consistent.
Most of us own a 12V DC car adapter already, so bundling it is somewhat excessive for most.
On a legal basis, these cameras actually move power from the innocent and places more power into the guilty, as it is a forward facing camera, proportionately more of the accidents will be one caused by the owner who can then delete the evidence. When hit from behind you are majority the innocent and yet Roav is not a rear camera. There is no side camera. There is no internal camera to show you were texting / distracted.
As such, such cameras are a minority gain to the innocent but a majority gain to the guilty.
