This is true Craig, but Highway patrol officers must estimate a vehicles speed before the release radar or speed detection devices. The radar etc is there to back up the officers observations, not the other way around. I wouldnt be confident in estimating a cars speed, but highway patrol officers do it on a regular basis so are classed as experts in the field.
The comment from the judge about the Police car not being able to go as fast as a lamborghini is true, but a police car can do 160km/h so where is the issue?
