Driving speeds

No conviction. How can he be certain it's not mistaken identity? Or, more to the point, how can the jury be sure?

:/
Who's identity is he mistaking? His own, or the guy who he pulled over and asked for ID?

I don't follow you here, at all.

In the UK, I usually drive at 65-70 in the conditions you describe. Better fuel economy, more relaxing than racing to get somewhere, and my car isn't great at higher speeds.

I do a lot of city driving which is way worse than the motorway, though with some effort it's possible to drive more efficiently.

The point is, the word of a policeman is not proof on its own. I mean if he pulls over someone who overtakes him at 90, but fails to record it, then it's the word of the copper vs the word of the driver. How can the jury be sure the copper pulled over the right car? The copper might be sure because he was there, but the jury can't be sure because there's no evidence other than the word of the copper.

Here, for the prosecution to succeed in getting a conviction, they must prove "beyond reasonable doubt" that the defendant is guilty. When there is only the word of one copper, it's much easier to cast doubt on his version of events, than if he has physical proof.
