The margin of error for something "one KM apart'' to gauge speed is very high. It's not "dead simple" like you say. Hard enough during the day, let alone at night and you need to know your set heading point. Start meandering from that point a bit and swerving around and it all goes out the window and impossible to do accurately. Also realize the cars are going around corners, covering more distance than a heli is flying in a straight line. The only things that exist for this are the white lines you see painted on the road. Those can gauge a speed within a certain margin of error. Try seeing one of those from 1500' up in the sky at night. Oh, wait... you can't.

Bottom line, they have no proof how fast these cars are going and saying the "whirlybird" is going 142kms DOES NOT IN ANY WAY mean the cars were going that fast. He could have been flying into a headwind and the air passing over the pitot tube and static port would be much higher, indicating a higher airspeed than actual. And because of this is why you do true airspeed and groundspeed checks.

The twist and turns on that highway is highly dangerous.

Lucky the group was stopped before anybody got hurt (other cars especially).

Of course it'd be my car, and NO I wasn't doing 140 kph.

That does not mean he can still obtain a conviction if he is trying to estimate your speed from a moving chopper at altitude. That's not part of the training.

What i meant is, visual estimation on the ground. i doubt the helicopter thing will stand in court.

Also, some strong logic here. Using the video from the chopper, they can estimate from different locations how long it took a car to travel from one distance to another and then measure the distance. Grade 11 physics brahs.

I was just doing 120 on highway 1 and was getting passed left right and center. Is that ok? Just wanted to run it by the revscene hero squad.

It does all the time. Why wouldn't it now?

Well let's see, from the video: pack is passing the Horseshoe Bay Drive exit at 23:49:30. They come up to the merge again at 23:51:10 or so - that's a minute and 40 seconds.

Looking at GMaps:

That's 3.5km covered in 1:40.

Plug that into a suitable calculator, like this one and we get 126km/h. Keeping in mind that they come around that corner and smack into a wall of cop cars, so they're all slowing down at the end of the segment... yeah, not unbelievable that they were going faster when the chase started. And it's still well more than 40k over the limit.

But you know, according to The Mighty Marco, it's IMPOSSIBLE to visually estimate speed from the air.

I'll just leave this here...
