I get the impression it disengages so that Tesla can legally say "self driving wasn't active when it crashed" to the media.

The cartoon wall is just an exagerated illustration of why a vision only system sucks compared to other systems.
If you watch the rest of the video, you'd see Tesla's vision only system is inferior to cars using radar/lidar in other, more realistic situations like heavy rain and fog.
I was working with a buddy on a "startup" that was more of a hobby than anything (and didn't go anywhere). The early prototypes were controlled by Arduino and Pis early on -- ease of software development was key as we experimented with and dialed in the hardware. The later prototypes used an ESP32 though, because we're aren't idiots.
I'm a hobbyist at best: it kills me that there are well paid "professional embedded software engineers" out there that can't work with actual embedded hardware. All I could think of was this article on electrical engineers that can't solder. The complete lack of real world, hands on experience with the hardware blows my mind.
They make a lot more than car navigation systems. Their recreational gear and avionics are top of the line.
