Right. It's no accident (badum-psh!) that Russia and China are full of expensive cars with dashcams. Or even just regular cars with dashcams. The benefits far outweigh the penalties for the vast majority of dashcam users.
Dashcams in Russia are used because there is a huge problem with insurance fraud people would just either get hit intentionally or even jump on the hood of standing cars and claim they were hit.
The police and the legal system in Russia wouldn't care about your dashcam if you want to get out a of a jam a bribe would work just fine (I've been pulled over in plenty of places where I had to pay dues, mostly Asia - Thailand, Philippines, Burma but it's not that uncommon in Russia and some Balkan states either), insurance companies on the other hand do like them very much.
I am really wondering why you are pushing so hard against dashcams. Dashcams (along with bodycams) are making corruption in the justice system much harder to pull off. You can find a ton of videos on YouTube exposing corruption in law enforcement around the world, including the United States. This is not mass surveillance! This is a personal record of travel that isn't vacuumed up into the warrantless surveillance machine and twisted to serve an evil purpose (like Verizon's call record database, among many others). Your argument -- that your video could be subpoenaed and you might have to explain why you were driving like a jackass -- is weak to the point that I am beginning to suspect an ulterior motive. Why are you pushing so hard against dashcams?
Nothing wrong with having a camera to record when you are being pulled over, having a device that constantly records everything and is pretty much turned on by default is disadvantageous to both your privacy and your interests.
I've also said that I personally would recommend a dash cam which records the last 5 min and no audio, this should be enough as a deterrent and will allow you to provide any evidence if required while not keeping anything on the record that could damage you.
And please do not compare dashcams to bodycams, because ?I'm pretty sure you would not want to live in a world where everyone is wearing a bodycam that is recording 24/7, or even suggest people to walk on the street while recording everything with their phones.
When you make a record of anything you should be aware that what ever you document can be used against you, or against another party at any time and that your agency to maintain the privacy of that record is limited both from a legal and practical point of view.
Uhm. Bodycams -- specifically that term, "bodycams" -- have exactly one context right now, and that's the context in which law enforcement wears them while on duty. And I do think that bodycams are a great thing that should be required as part of being a law enforcement officer on duty.
You still haven't explained yourself beyond the same old "what you record can be used against you" argument, which as I've said before, is weak. I think this will be my last reply, since there is absolutely nothing being gained here in this discussion.
The simple argument is that if you were involved in an accident with a dashboard camera it can be used against you, if you tamper with it after you are stepping into the territory of spoliation of evidence.
Ask any lawyer and they'll give you a golden rule - do not create records that might be used against you unless you are compelled to do so.
If you have a dashboard camera then know the risks and mitigate them as I've mentioned before having a camera that overrides it's footage after a short period is good enough simply because you then need to perform a deliberate act to save that footage this reduces the liability that a dashboard camera can present in cases where it might have recorded something you might not want to become public.
Furthermore dashboard cameras that do not record sound in the cabin are also preferable because the last thing you want is you on record being distracted by arguing with a passenger or switching radio station or bad mouthing some driver that cut you off and those things are considerably more common than people think.
A dashcam that overwrites footage in a short period may be of no use if you're unable to stop the recording because you've been injured in an accident.
And anyway, if I'm at fault and that is recorded on the camera then that is okay with me. The camera will at least give an indisputable account of the events it recorded, whereas our human memories can be ... inaccurate.
