Separate day and night settings i think are a good idea in dashcams, not least if it is a new camera capable of doing more things.
The WDR performance of the B1W could be better as the pictures above also show, but its not a super big thing for me personally.
I have been looking for other things, like phones and so on, supporting the European GALILEO system, but support for that are still small in things, GPS / GLONASS & BEIDU are pretty much the norm today.
Speed cameras i dont care much about, they are all warned with a roadside sign here well in advance, and we only have like 10 of them in the whole country, the Danish police rely on mobile ATK vans for speed measurement, and once in a while cops with the laser speed gun.
So as a Dane you need updates live and not just 2 times every day the police with laser gun, or the ATK Vans operated by non police people are only in one place for a hour or 2 then they move on to a new location
ATK = Automated Traffic Kontrol, so you park the van, line up the cameras with the road and press the button and start making money.
CPL filter i think should be in the box with any dashcam, as a optional item it is a little bad.
And yes there are good and bad things with most if not all dashcams.
