This feels like a regression, mirrors are really high resolution and are great with depth perception

And better color response, no latency, getting some dirt or leaves splashed on your windscreen doesn’t take out the entire field of view…

On my car the camera is placed such that it rarely gets blocked by dirt or debris. I sometimes flip back to the mirror only to find I can't see anything due to dirt on the rear window. Flip back to camera and I see just fine.

Counterpoints:

I can't see shit out of the back window without some work on my part on many cold mornings (with electric defrost), but a tiny little camera-heater could be both fast and efficient (which is more important for EVs).

I can wipe a small camera lens off faster than I cash wash a uselessly-filthy back window enough that it is better than a streaky opaque mess, as I've had happen to the back window on fairly mundane (if long) road trips with regular road grime.

Fewer windows means a cooler interior when it has been baking in the sun

It's a lot harder to get distracted by light and glare from phone screens or whatever that back-seat people are using when there's no interior mirror pointed in that direction to begin with

It doesn't sound all bad. And since it's got rather good cameras, that sure does sound better than the vehicles I've spent time driving that had neither rear windows nor any cameras.

Sat in the rear, it feels claustrophobic. I’m told they will solve that with extra daylight lighting installed behind the rear headrests.

Extra daylight lighting? I love it when problems that should not be are so highly engineered.

Or, they could "solve" it by installing extra screens on the walls showing ads for package holidays. Of course, that would raise the temperature inside, but it's something that could be solved with extra AC, which would need large batteries and more frequent stops, but that could be solved by... seems to be the way of "innovation" these days, we no longer fix what's broken, but break what works and charge extra for it.

Driving without a rear window isn’t a big deal - see, for example, nearly every cargo delivery van on Earth. I have to imagine the stubborn refusal to add standard physical controls back to the cockpit has more potential for trouble than an impeded rear view. I wonder if there’s NHTSA data on this specifically for passenger cars? Maybe incidents caused by blocking the driver’s rear view (with furniture or people or w…

Yeah, it's totally fine, as long as you have both side mirrors. It'd be nice if they put bigger mirrors on the side if they're killing the rear window though. Although they're pushing a screen to replace the mirror, I guess.

I haven't used one of those in a while, but I did have a rental with a screen / mirror and found it really strained my eyes to change from far focus on driving to near focus on the screen... Might be better when the screen is not also a mirror, I could kind of see the mirrored image if I was far focused even if the screen was on... it was pretty distracting until I figured out how to turn off the screen part.

Whilst it feels strange initially and I caught myself thinking why? Most car reverse cameras for 360 degree cameras provide very good visibility outside of the rear of the car. I don't necessarily see the problem with having a rear windscreen, but that's up to the buyer

On cars I did drive a rear view camera allows to stop exactly were you want but gives a poor situation awareness. Also the wider camera angle the smaller are objects on a screen - there is no such problem when you can turn your head around to see with your eyes.

On the flip side, camera rear view can have automatic gain, so you can see much better in the dark. It can also have a better view due to placement. And as a bonus, no need to adjust between drivers. My car has both in a combined unit, flip down for regular mirror and up for camera. While I initially thought it would be a gimmick, it didn't take me long to realize I preferred the camera view. That said I wouldn't wan…

Sounds like progress. I’m struggling to see any functional downside. Resolution is good enough at that distance from screen (and you generally not need much resolution - just identify a hazard).

You don’t need to move yourself around since view is wide angle.

OT: carbuzz.com estimated its curb weight as about 5,500 lbs.

That’s good when you’re driving 80mph on the freeway, but way too big around town.

I’d like to see drivers in US cities have the option for something smaller, like Renault’s new Duo, the replacement for the Twizy:
