According to the Declaration of Helsinki, "the well-being of the individual research subject must take precedence over all other interests".
So it's a little worrying that four speed cameras on South Yorkshire roads have been switched off on an "experimental basis". We already know what the result of the "experiment" will be - in a similar exercise in Oxfordshire, the incidence of speeding increased 88%. And there's a pretty well-established correlation between speeding, and, well people dying in crashes.
Should the authorities be "experimenting" with people's lives? Is this not, like, against their human rights and stuff? Oh sorry - I forgot. The right to drive is the most sacred, inviolable human right of all.
