Only 1080P in this day where 4K is de rigueur, and 8K is already on the horizon? Also, when is somebody going to include a solar panel for these things so that they JUST WORK all the time? ...and some kind of permanent affixation that will prevent attempted theft?

captainWell, you could have a camera with 4K, but noting how long trips are, note the amount of storage that 4K video is going to require (hint: a lot). Having said that, not the duration of time is going to take to fetch that asset from this device via WiFi to your local storage and else where. I mean, if you truly want 4K, that's great, but for me, I'd be more interested in a good lens and a good light sensor as well as decent stabilization techniques.
I think the solar panel is a decent idea, but then you are getting into the arena of needing a battery to go with it: Honestly, nothing is stopping you for pursuing making a solution for that.
The theft is a good concern. I presume some people like the idea of simply popping it off when they are finished driving as part of their routine, but I can see there being those that would rather have it the other way.

hasuesThose are all valid points. I think that h265 compression shinks 4k down to less than double what the same video in h264 would be, and I’d only want to offload short clips for legal needs very occasionally—I hope! ;-)
My problem with HD is it just doesn’t have enough resolution to pick out details like license plates and faces—details required for criminal pursuit. However, what I most want is speed, location, and TWO WAY video for those times I get stopped “speeding” when I know I was not. I haven’t found a solution yet, but I have hope. :-)

captainI've played with h264 and h265 and there are some interesting results on the amount of storage that can be saved, and perhaps that helps. As the storage sizes increase with microSD, that gives one hope for the size that can be stored which results in larger video assets. Obviously, one could simply make a custom storage for such, but depending on one's travel times and implementation, I don't know how much of a necessity that is. The other factor is noting the more sophistication one has with their encoder, the more power consumption and computational power needed to get those results. Again, probably not an issue here, but I'm just making sure that is recognized.
To sort that out, I guess I would have to ask about the implementation. Do these dash records run all the time regardless and at the end you simply take your clips off if you choose? Or do they activate based on an event such as a button press, etc to tell it to start recording? If it is the latter, then I would think it would be reasonable to use 4K.
Regarding the comment about HD not having enough resolution to pick out a license plate and faces, I would think that it would, but I think the quality of lens and sensors would be an issue here. Don't get me wrong; I recognize that the more pixels one has for producing an image, the better definition one has. I guess I base this on the quality of cameras that have been used in the past for this work. Typically, many of these solutions have a better analyzer to know how to recognize these plates and such. Granted, it sounds like you are discussing your ability to see the license, but I note that people have approached this issue on their own: https://medium.freecodecamp.org/how-i-replicated-an-86-million-project-in-57-lines-of-code-277031330ee9
If you could modify the recognition part of code, read the coordinates of the image where the plate is, then have a camera system (like what one finds in cell phones for example) and have it zoom on that location for the read, that would be a decent method for handling it, but I'm deviating from the original purpose as you are stating you simply want the clips to be recognizable for a human and not bring AI in the mix.
That being the case, I really think you would need a much better camera system to get the results you want, so I think you would be justified in passing over this system regardless (unless you can get a try before you buy).
