There's a clear problem with the balance of what police should bother about and not bother about.
Clearly this man (or woman) did a journey and didn't injure anyone. Still, every day, we see people reading maps, talking on the phones, reading the paper, putting make up on, etc etc.
I bet you that this person was 100% focused on the road and had extreme road-awareness. Speeding in 30mph areas isn't nice, but at the same time a speed limit is only a mathematical limit set to the lowest common denominator (school-run-mother-with-4-kids-in-the-back-with-no-interest-in-the-car-and-putting-on-make-up-whilst-answering-the-mobile-phone???), sadly it's policed like a religion. Common sense and skill need not be applied.
I'd rather see the police's efforts put on tailgaters, red-light-runners, stop-sign-ignorers, "I-didn't-look-you"s, etc.
I agree that he should have edited the video, tho'!
Just remember; speed doesn't kill - but the sudden lack of speed can.
