The law makes no sense, but that's why we have officers and judges to enforce and interpret the laws.
During heavy rains or dense fog, driving conditions become unsafe at the normal posted speed limit. You're not breaking the law by driving the speed limit, but you ARE driving at unsafe speeds considering the road conditions.
That's where the police officers come into play. It is up to the officer's discretion whether or not to cite you given the circumstances.
Beyond that, there is court and a judge if you wish to contest the citation. That's where interpretation of the law comes into play.
