Speed limits are set so low that it's actively unsafe to adhere to them in many places. It's not unreasonable for self-driving systems to acknowledge that... in fact, it's more or less mandatory.

Give me a break. This is classic prisoners dilemma, where it's better for everyone to speed. However the ideal outcome is for everyone to follow the speed limits. If law enforcement would prioritize enforcing this law we could have full compliance. There's no problem with 55 on the interstate. The problem is unskilled or otherwise distracted drivers, which can also be observed at 55, and are much more fatal at 70+.

Statistics say otherwise, but hey, enjoy the rest of your bus ride.

Incredible stuff that the regulators are so absent or neutered that such a feature could get shipped.

These would be the same omniscient, benevolent regulators who intentionally set speed limits well beneath the 85th-percentile rule where highway safety is optimized? (Well, no, those would be different regulators entirely, but still...)

Speed limits aren't about being able to stop everybody, they're about being able to stop anybody. If nobody exceeded the speed limit, then rest assured, it would be lowered further.

The answer is right in the text of your question: the 85% rule of thumb is for highways. If it makes you feel better I've seen a proposal to offer a discount on speeding tickets in Texas if you pay with bitcoin. No, actually, I made that up. It's funny because it's so very plausible.

Surely this will help with the regulatory review of the legality of FSD.
