1. ## speed by sight

http://watch.ctv.ca/news/latest/spee...ht/#clip352687

freaking hilarious. Make sure to pay attention 3/4 of the way threw. Where the TV spokes person is holding the radar gun and the officer is guessing oncoming traffics speed.
(by watching the radar over the guys shoulder)

3. Any ways to get money to pay for those Olympics !!
It's just the beginning....

4. It does appear the cop was looking at the radar gun in the reporter's hands. No wonder he's an expert.

5. TV news makes you stupid...

6. This is registering a full 10/10 on the bullshitometer!
LEO certainly appeared to look at the radar readout before each "estimate".
But we all know Police integrity is beyond question.
The whole situation is farcical. Next they'll be ticketing people they think are likely to speed

7. the speed shows up on the heads up display(the peep hole), how do u suppose the cop could see it through the reporter's face?

8. How do they show it to people they've just nabbed then? As illustrated in the same feature.

9. The whole concept is flabbergasting.

You can be accused and sentenced without evidence.

No chance of disputing it, because it's all fabricated from thin air.

How can you possibly visually calculate the velocity of an object approaching you dead on, without reference points?

Velocity = distance / time

Without at least two reference points, with known distance between them, and a brain with 100&#37; accuracy in the calculation if time; how can a LEO possibly with good conscience give you a ticket based on visual estimation.

Unbelievable. Officers are not machines they make guesstimates just like everyone else.

They can use lamp poles for reference points. Each lamp post is 50m apart. I thought you would know this with your physics.

11. I don't ever remember being taught that lamp posts were 50m apart in my Physics lessons. Maybe it's different in Canada

12. Question, when you're waiting to turn left, or pull out and watching oncoming traffic can you look at an approaching car and estimate their speed? In other words, can you say that guy's going 50 so I can pull out, or that guy is hauling over the limit I better stay parked?

If so congrats, you've just performed a visual speed estimation. If you can't I may see you here starting one of the threads with a lot of !@#&**++< in the title.

Other random thoughts; if you get pulled over don't tell the cop you don't know how fast you were going, don't say "what" & don't go on the news saying you'll contest a ticket in court unless you've got deep pockets. All you're doing is making sure the cop writes up some solid notes for later.

There is also an lcd display on the back of almost every lidar/radar gun as well as a HUD. The cop is clearly looking at the back of the gun prior to his "Visual Assesment"

14. Pathetic... "Veteran traffic police" indeed!

Even if the "Super" cop has some reference points and some really good math skills....there is a margin of error which would allow people to still be over the speed limit and not get caught by the "Super" cop. A general rule would be a margin of error around +/- 10Kmh for radar....so a manual guest-imation would have to be in the area of +/- 20kmh?

This is purely another cash grab...propaganda...an attempt at justifying any officer giving a speeding ticket...even the ones that don't get the radar/laser guns. If they had to limit speeding tickets just to officers with the expensive gadgets...then their revenues would drop.

16. I don't doubt that after observing 'hundred and hundreds' of speeders you begin to get a knack for this sort of thing... but my god man....take your day-glo vest off and go stand over there, IN FRONT of the gun, THEN nail your 'ballpark' guess of 62kph and I'll ooo and awww ... I'd be much more inclined to believe the guy if he said something like "between 60 - 65 kph", but glancing down and saying the exact speed, .... right... maybe I'm just skeptical, but this is far from empirical evidence of their estimation skill...

....the real question is, how many jellybeans are in the jar?
