The answer is for the car to always drive according to the slowest speed allowed. So, it's always 25mph in that zone. Changing it based on "school hours" is a bad idea anyways.

This isn't really safer. Driving behind a driver not keeping up with traffic and breaking erratically is a traffic hazard (happened to me a few days ago with a human driver).

  It's generally a bad idea to fit safety regulations around the safety limitations of the item they're regulating. We set speeds, sometimes based on time of day or presence of children. Humans handle this just fine. If your car can't, then the car needs to be fixed or it's "self-driving" functionality entirely disabled. Changing speed limit laws to compensate for these limitations is entirely the wrong direction.

    My point is that FSD needs to be at least as capable as a human to follow speed limit signs. The problem generalises - it's also unacceptable for FSD not to keep up with traffic on a freeway or randomly throw in the brakes to avoid spurious hazards for the same reasons.

  I remember the story on here a while ago about a self-driving car that got rear-ended because it stopped in the merging lane of an empty highway rather than accelerating like any human would...

In Australia, it's not just little side roads that run by school entrances that have this rule; the school zone thing applies even on fairly major free-flowing roads. Two examples I can think of are https://www.google.com/maps/@-37.9293496,145.0051951,3a,59y,100.02h,97.62t/data=!3m6!1e1!3m4!1sw3DtJ1A3rOthzLwiFu_vAA!2e0!7i16384!8i8192 https://www.google.com/maps/@-37.9293496,145.0051951,3a,59y,... https://www.google.com/maps/@-33.7710688,151.0985503,3a,75y,108.23h,76.34t/data=!3m6!1e1!3m4!1sprRfDx4VubtsH8t7Kd_IJw!2e0!7i13312!8i6656 https://www.google.com/maps/@-33.7710688,151.0985503,3a,75y,... As the usual speed limit is quite a bit higher at 70km/h, driving at 40km/h (25mph) outside these times would make you, at best, a rather annoying obstacle to surrounding traffic.

If I go 5 mph slower than the speed limit I have had people pass me on the right, this seems less safe…
