As someone who characterizes image sensors for a living, I must say that image sensors are still driven by portables market, meaning you have small format size, small pitch that dashcams have to use because it's a niche market.
I would have prefered a 1/2" or larger sensor with a larger than M12 lens for better clarity and more light capture. Sure OV makes 2.2um+ pixels (using older technology nodes), but where I see it, there's still a lack of low light collection.
The future looks brighter because:
1. the resolution chase has taken a back seat due to pitch size (1.1um commercial, 0.9um R&D)
2. technology nodes keeps going down (65um commercial, 45nm R&D, maybe even lower in R&D)
The lower the node size, the more room there is for pixel charge storage, by increasing capacitance of the pixel storage, you increase the low light sensitivity. Noise is always an issue of course, and with higher capacitance, the noise increases, kTC. There are implementations and uses of active noise reduction circuits, but they have their own trade offs like lower speed due to increased timing demands, and others.
I suppose because it's a niche market, the processors have the same fate, that's why you don't see 1080p60 quad channel processors out there for example, or even 1080p30 with sufficient bitrates. The EV market however will help the imaging industry realign some priorities, like global shutter, depth sensing, night vision/low light, etc.
