That is actually a benefit for low light conditions. Less resolution = bigger pixels = better efficiency.

The ON Semi documentation suggests its a 1/3" sensor size: https://www.onsemi.com/products/sensors/image-sensors/ar0136at https://www.onsemi.com/products/sensors/image-sensors/ar0136... Your iPhone 13 has a 1/1.9" wide sensor, significantly larger... and multiples of them working as a team. Even if we go back to 2018: the Google Pixel 2 has a 1/2.6" sensor, still much larger (and with better resolution) than what this Tesla is using to see the road. ---------- If you want better night vision, then use a bigger sensor. Its just basic physics. A sensor with 2x the area will capture 2x the photons. Complaining that this car can't see the road at night... well.... yeah. Its got an tiny camera sensor. What did you expect? Its got bad night vision.

  ADAS must use qualified chips and that one was a pretty standard one some years ago. I like others better, but you must see them in system context and be able to continuously process that stream. Given the power budget and other constraints this was what a number of manufacturers ended up with. After all these guys are not dumb, they just need to desing in many more aspects than mobile phones.

    That's a good point and some basic searches seem to confirm your assertions.

      I hope so, I'm in that field since 2003, started with the first night vision system in series production and built an number of those systems since. One of the problems is tenperature range. Driving continuiusly in Death Valley can heat up your camera to the point it runs away into thermal self destruction, if you don't take counter measures. This is not a problem for mobile phones. Another issue is continuously processing uncompressed data. Mobile phones compress with hardware support, especially in video mode. I had one of my mobiles shut down during a long video conference. This must not happen to an assistance system.
