Well, let's see if someone can come up with another (reasonable) answer.
In a free society - which our's is supposed to be - laws are supposed to be backed by a good reason. It's that reason I'm looking for. But, sadly, I don't believe I'm going to get any reasonable answer.
Does the reason have to be rigidly logical and based on known truths? It could be a politically or financially expedient decision, while speed limits have a loose connection to safety they are relatively simple, i.e. cheap, to enforce and most people understand that going too fast is bad so it makes sense in a limited way. Hammering an inherently fuzzy system down to a binary one is on the face of it ridiculous, however it does lend itself to having a simple rule which is easy to comply with and prosecute if disobeyed.
A driver may feel aggrieved at receiving a speeding ticket when they do not think they were doing anything unsafe, however they will generally accept that they were breaking the law. This ignores the issue of incorrect readings of course.
Now imagine that a driver was issued a ticket for driving unsafely for the conditions based on the opinion of another person, how likely is it that they would feel this is completely reasonable?
Given a choice how many drivers would want a system with uncertain and subjective parameters to avoid prosecution in comparison with a value which can be easily complied with when there was any likelihood of being caught.
Sorry, rambling a bit there Pete without supplying a 'good' reason, mainly because I doubt there is one other than the expediency I suggested at the start.
Believe it or not I still had the OT in mind.
Perhaps it is wrong to think of VAS as a reminder of the speed limit in order to avoid being snapped by a camera and more of a tool to alert a driver to the idea that they should approach the hazard at less than the speed limit. Not that they really do that.
