75kmh ===46.6mph

A Palmerston North mother has labelled police claims that her [16 year old] son reached speeds of 75kmh on his bicycle as "bizarre", saying it was impossible for him to go that fast.

Summerhill Dr, Palmerston North, Manawatu-wanganui 4410, New Zealand

I'd agree with the mother.  A mere teenager would probably not have the strength to travel at 75 KPH, even with the hill and all.

That's a lot for gravity-drive, and even gravity + power. The aerodynamic-drag would be substantial at that speed. Still, I don't know the hill or the boy, or the bike, or the equipment used to "clock" him.

It would be hand-held laser speed recorders, if the the cop was parked there monitoring car drivers, coming into the city downhill, its a good place to make up time before you encounter all the traffic lights once over the bridge, but if the cop was driving on patrol then it would be radar that did not need pointing.

But a boy on a bike would be a small target for a laser mean for cars and bigger vehicles, and with radar, a boy on a bike would not reflect radar that well.

Knowing cops, i think it was really just the cop was on patrol and saw the boy, and just did a estimate, high enough to shock the boy into not doing it again, if equipment was used, the reading would not have been accurate due to it not being meant for boys on bikes, that could explain the 75Kmh

if that was the case, the cops would not admit it, it would mean one cop did not understand the limitations of his equipment, later it could be used as a defence for a real speed case, and then, it could be the equipment is discredited, and become legally useless.

Did you think, that if the boy was risking killing himself, that the same went for the father on his test runs? The boy got away with it due to his age,.

I will advise if the father gets charged for a offensive after the news report came out.

They track baseball pitch speeds with radar.  LADAR would be overkill but would do a better job of it.

 The device the cops here use looks and is handled like a gun, but bulky
Yes, somewhat like a hair dryer....

 Why not see what happens if you park your car on the side of a road, and point a hair dryer at on coming cars.

What if a few cops did the same idea but pointed a paper cup at on coming speedsters but used a hidden radar device to clock their speed and charge them?

Word would quickly get around and speedsters would slow down whenever seeing a commuter in his car on the way to work drinking a cup of coffee

Would work better than parking dummy cop cars on the side of the road

It's been done.....the cars slow down, but if the police catch you doing this, you are "endangering the public" because some will "apply the brakes unnecessarily hard to get slowed down" making their swerving and skidding a hazard.

The problem with your theory is that, the many of the police are under a quota system, and so they are not there necessarily to make things safer, but to get their quota in speeders (thus the reason for hiding just over the crest of hills so radar detectors fail more often, etc.).  If they were there to actually "just slow down the traffic, they'd be out in the open for all to see,  maybe even a car (doesn't have to be a real one) every 10 miles or so, so the drivers don't KNOW which ones are real or not.

 Quota system

If so, why dont the cops ask for volunteers to help get their quota each day? :-)
in this case, that would be "illegal"  as they are "civilians" and asking a civilian to be less civil is not really a good idea.
