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?
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.
