Can 3 bikes get clocked by radar?

Cheers for the feedback guys, was genuinely curious.

As said before, everyone speeds, getting caught is just a matter of when.

Try telling THAT to the rest of KB...

Said it before on this thread, I'll say it again..."This is quite entertaining watching all you armchair experts/bush lawyers talk about something you a) aren't trained to use b) aren't certified to use and c) have no experience in using".

Akzle, you should be a biking agony aunt.....

"Dear Akzle,

the other day the police got me for speeding again help!

Yours, Buggered."



"Dear Buggered,

if the cops weren't wearing their hats, they have to pay you compensation.

Akzle"

Dunno about armchair expert... Would you consider someone who operated radar on a surface-to-air missile system and went on to become second-in-command of a whole sector an armchair expert? I am not rated to operate your typical popo radar, but I certainly feel qualified enough to comment on the inherent shortcomings of such a system. And besides, I'm a pompous prick, so I can comment on whatever I like.

I used to have a laser pointer on a key ring.

You are qualified.

Comment.

You are qualified.

Comment.

Id say over qualified

The radar first gets it's own speed by getting a reading off a stationary object (it needs to be dead ahead of the vehicle), then it takes a reading of the closing speed of the popo car and you, then it subtracts it's own speed from the closing speed to get your speed. This is where the problem is:
The cosine effect that was in your favour is now against you. If the own speed reading is taken off something that's not dead ahead, then it under-reads. That makes your displayed speed read high, and you're nicked, sunshine.

The worst case is when the returned signal is from a moving vehicle in front of the patrol car. The patrol car speed is not correctly recorded, the closing speed on the vehicle in front is used thus severely inflating the calculated speed for the approaching vehicle.

Many have said that speed camera radar error caused by a target vehicle not traveling toward the camera at the calculated angle is negligible.

Its actually a worse case of 8%, for a camera at a design slant of 22.5 degrees, which I'm told is what we use.

The camera would have to be severely misaligned for this to occur, or the camera would have to poorly sited on a corner, or the vehicle would have be changing lanes quickly etc.

I accept its not likely, but its still entirely possible, and its not completely acceptable in my view to discount the possibility.
