Earlier quoted context omitted.
The reason speed limits make such a great example for these arguments is because they're a preemptive law. Technically, nobody is directly harmed by speeding. We outlaw speeding on the belief that it statistically leads to and/or is correlated with other harms. Contrast this to a law against assault or theft: in those kinds of cases, the law makes the direct harm itself illegal. Increasing the precision of enforcemen…
This unwritten distinction exists only to allow targeted enforcement in service of harassment and oppression. There is no upside (even if getting away with speeding feels good). We should strive to enforce all laws 100% of the time as that is the only fair option. If a law being enforced 100% of the time causes problems then rethink the law (i.e. raise the speed limit, or design the road slower).
Of course technically option a is violating the law but no sane police officer will give you a fine in this case. Nor should they! A robot will, however. This is stupid.
