Problem is that EIS doesn't work well for this type of vibration, it is good for unsteady hands where it can source the image from different parts of the image sensor to correct for the movements, but the high frequency vibrations you get in cars that cause motion blur over a small number of pixels can only partially be corrected, EIS can't undo the blurring of the pixels, only correct their position, especially at night when the pixels can get seriously blurred by the vibration due to lower shutter speeds.When I look back at my old 402 and 412 they would have benefitted from IS. When you look at the footage you don't immediately realise until you look closely at the parked windscreen wipers how much vibration is transferred to the dashcam via the ball joint system.
The 412 footage was good on smooth motorways but not so on poorly maintained town and country roads.
Take the dashcams that have a solid mount and they stay rock solid regardless of road surface and the wipers and dash don't appear to vibrate.
The answer to vibration on a dashcam is to use a solid, vibration free mount, then you can use the full sensor resolution for plenty of detail. As you point out, there are plenty of dashcams that succeed and prove that it can be done.
