Like Skynet in the Terminator movie series, the computer in a speed radar in Montpellier , France took control. The radar probably realized that it was not issuing enough speeding tickets, so it changed the rules of the game.
On a road limited to 110 kph, it started making photos of cars and motorcycles that were travelling faster than 90 kph. In other words, it had gone mad, but it was a bonanza for the government. Maybe the radar could start fining vehicles over 10 kph?
In fact what really happened was that local authorities changed a road's top speed limit to a variable speed limit. Between 7 and 9 AM and 5 and 7 PM, the speed is limited to 90 kph, while the rest of the day speed is limited to 110 kph. Nice, but someone forgot to tell the radar.
Now they have had to close down the radar and scrap all tickets issued recently by the "crazy" radar.
Ahhh, don't you love government communications? One part doesn't know what the other does.
