Someone sent this to me as a protest against a new mobile form of radar the police and gendarmes are using. Personally, I think protesting new technological advances is not productive and the more the police can do to prevent speeding and reckless driving, the happier I am but this shows how the new systems work so I thought it would be interesting to pass on.
