Why? Because of shadows or does it operate on a 2D 'view' of the traffic situation?

IIRC it's an vision-only ML-based system. So the answer to "why" is probably "we don't know lol"
Right. Scary stuff. I'm not excited to drive a cheap second-hand ICE car, but the fanciness stops at AC and 3.5 mm AUX-jack on the stereo, and that's pretty nice. If I wanted to I could do service and repairs myself.
You can also just have a dumb EV and thus do a favor to both your own safety and the survivability of the planet. EV does not automatically entail AI-assist.
I'm not very well informed in this area but I suspect there are no serious alternatives. Ignoring price, are there EV:s that can travel at least 500-600 kilometers on a charge but only weigh 1500 kilos and hence are rather simple to lift with consumer or improvised tooling? Are there EV:s without remote control and 'upgrades'? Can I change lamps and shift tires on such EV:s? Do they fit at least two child seats or is that amount of space more of a premium feature?
The existing EVs' specs are more than enough, don't worry.

And yes most of these EVs are still pretty dumb, so you'd like them. It's just that Tesla got the hype.

By the way, when you realize that you actually never drive for 500km straight without e.g. several 30min pauses to rest, which can be used for charging if you have an EV, you discover that you have much more options than you'd think to choose a model to buy. (most governments officially advise it, as not doing pauses would endanger the lives of everybody on the road)

Seems it's rather common that they're Internet connected when I look at some ads. Do you have an example?

30 min pauses? Why? I stop for five-ten minutes every four to five hours when I need to pee, and I can't rely on there being charging stations along the way.

Image segmentation is almost a solved problem. There is no reason why it should get confused even with a vision only system. Their problem is most likely that they don't have enough compute to process a history of frames and instead process a single image at a time leading to jumps in the segmentation results and those random jumps cause unpredictable braking.

So people keep asserting. And yet here we are.

Almost pregnant.

In my experience it's almost always shadows. I can't be sure of course, but I've definitively noticed a correlation: both shadows from overpasses or shadows from semis, this happens more often when the sun is low too.

It never happens at night though, which in my mind makes the shadows hypothesis weaker.
