Chris Tolley (ukonline really) gurgled happily,
sounding much like they were saying:

Speed cameras, like many other automated processes, make decisions
based on a previously defined sets of circumstances. In this case IF
vx THEN take picture. Making such decisions does not infer that the
machinery involved is intelligent. As the cameras are, alledgedly, to
enforce safe behaviour then the decision process programmed into them
can be presumed to be intended to choose between safe/not safe.
Therefore, as far as the camera's programmed instructions are
concerned, IF vx THEN the vehicle is being driven safely.

No, the cameras are there to enforce the speed limit. That is all they
do. Someone could be driving their car sideways, but within the limit.
It's your assumption or the assertion of others that cameras monitor
safety. And it's a flawed way of looking at it.

I think you might find you're agreeing with him, y'know.
