writes "This article from the Montreal Gazette reports that a driver got 18 months in jail for speeding that killed a man, after the black box in his car revealed he was going 157 km/h (98 mph) in a 50 km/h zone in downtown Montreal. The recording device, which stores data on how a car is driven in the last five seconds before a collision, showed that four seconds before impact, the driver had the gas pedal to the floor and didn't brake before impact."
writes "Setting a precedent for the Canadian legal system, a Quebec man was convicted based upon the incriminating evidence found in his own car's black box."
