The slow driver isn’t creating the danger though. It’s all the drivers going over that actually create the danger you describe. If everyone just followed the laws, the danger you describe would no longer exist. Normalization if traffic violations is compounding the problem of the danger we face on the roads. So many problems could be solved and so many lives saved if people just followed the laws. The fact that everyone isn’t following the laws doesn’t need to be accepted as status quo.

It literally is the status quo. If I were still working on autonomous cars, I'd be much more inclined to work into the true status quo rather than imagine the status quo ought to be different and build towards that.

The status quo is also that people don't pay attention and are rude to pedestrians/cyclists/each other and ignore rules all the time (ever try waiting at an unsignalled crosswalk on a busy 4 lane road?). The one thing that I can't wait for is traffic enforcement by autonomous vehicles.

In Arizona, it is not against the law to drive over the speed limit. But it is against the law to speed, or drive too fast for the given conditions. Driving over the limit is evidence that you might be speeding. If everyone else is driving above the limit, and you aren't, you are the one causing the danger.

Your description does not seem to be consistent with my reading of the laws that are referenced from this page: http://azbikelaw.org/speed-limit/
