Bonus points for a cam that couples 4K recording with image stabilization.

Clips from a lesser 1080p HD cam might turn to mush when you do that. 4K may seem like overkill in a little device, but it allows you to better zoom in on details in a video clip and read small text like license plate numbers.

I'd avoid dash cams that only use internal memory and don't allow you to insert your own card, for capacity and convenience reasons. Some dash cams come with a card, but it's usually a scrawny one so plan on buying your own. How much video a given card size will hold is determined by the specs of the camera as each will use different levels of video resolution and file compression: It's not possible to say that xx GB of storage will hold xx hours of video across all cams. Memory cards are cheap, so buy the largest one your camera can handle. The bigger the card, the longer that 'loop' of recorded video you can mine for a clip you want to save. Every feature beyond that is optional and, often, superfluous. Then realize that all dash cams have the same core purpose that makes them unique among digital cameras: They record live (not time lapse) video as you drive, running in a continuous loop, the 'length' of which varies by the amount of storage in the cam.
