According to the BBC, Northamptonshire driver Shaun Davis was has been imprisoned for 28 months and given a 10 year driving ban after police found videos he'd recorded of his speedometer on his smartphone. David was apparently arrested "on an unrelated matter" which led to the police examining his phone. While anybody convicted of driving at almost 200 mph on a public road deserves severe penalties; I'm troubled by the methods the police used to prosecute and convict Davis. I'm almost certain that in the USA, with our Constitutional protections against both self-incrimination and unreasonable search and seizure, that a decent legal defense would have prevented this conviction. I don't know what, if any, other evidence the prosecution provided. Were there eyewitness reports of high speed runs on the A45 at the time? Did the prosecution provide GPS or vehicle data to corroborate the fact that the vehicle had reached the speeds in question? We've all seen crazy things people claim to have recorded on their smartphones. But getting two years in the nick; and a ten year driving ban; seems like a high price to pay for sharing your stupidity on social networks. One practical thing to keep in mind: The way speed enforcement is carried out in Britain is very different from the way it is done in the USA. The British police rely - to a very great extent - on Speed Cameras to do the job. Road patrols by police vehicles are, compared to the US, relatively rare. But since Cameras are usually in fixed, known locations, drivers familiar with the highways can speed with a certain amount of impunity.
