About 1000 warning radars have been installed in France, used to indicate the actual speed of approaching vehicles by a screen towards the road and warning the riders-drivers about the license points that they would be fined. 

 


However a French blogger discovered that it¢s very easy to hack the unit by a laptop, a Bluetooth connection and a software freely downloaded beforehand. The four digit code is provided at the manufacturer¢s website and guess what, the installer hasn¢t changed it. The result may be quite spectacular. Any more polite suggestions?
