Purely out of curiousity

[MichaelB]

Slipstreaming buses is just reward for all you hard work on your own in my opinion. It really is satisfying to go so quickly with such little effort. Whats the point in living if you dont take risks. As long as you are endangering just you then I dont see a problem.

I was riding over the penines recently and on the way down with a wind behind me my poor little bike was seeing some ridiculous speeds which would have brought on the most pain I have ever experienced if it had gone worng; but it was such a memorable day. I did however experience that pain trying to get back up the mountain(!) with a head wind but that was the last thing on my mind on the way down.

Nice thought, but it takes two pictures to get a ticket issued. The speed is accurately calculated
from the distance travelled in the time between the two snaps. OTOH it would be immensely satisfying
to get into the two pictures triggered by a speeding 4x4 and know that both of you were above the
posted speed but only one of you will be finding that letter on the doormat.

I've left it a bit late to die young, I'm afraid. Maybe I can achieve it before I'm a complete
geriatric.

A **** double decker OTOH may not be capable of doing 40. The problem with the modern buses is
that they have pretty zippy acceleration so hanging on up to their cruising speed is more difficult
than in days of yore.

Only if you are in a 20mph zone.

Yup I trigger the one near me. It helps to calibrate my speedo

_Some_ of the cars

I thought that the speed was calculated by radar, and the second picture was only used in the case
of a dispute.

A couple of weeks ago I apparently set off a 30 mph flashing signs in Horingsea, Cambs. I was
cycling into a strong headwind on an unsuitable bike, probably travelling at about 10 mph! I didn't
see any cars that looked like they could have been responsible. Most odd.

Nope. First flash fixes your position at the start of the measured distance. The second flash occurs
a known time later and fixes your finishing position. Hence your velocity can be calculated.

Interestingly, a fire fighter I know who lives locally tells me that when they are on a "shout" and
get one flash, they ignore it. If they get a second flash, they have to report where it happened so
that they avoid prosecution. I know it would be fairly obvious from the photo that its a big red
fire engine - but they may have not been traveling to an emergency and hence would have to keep to
the speed limit!

Indeed, the photos is really there just as evidence of the car that triggered the camera, and also
it can be used to calculate the speed as well if for some reason the radar speed reading was
challenged.

I've seen 'em go off (single flash) when there has been no sign of fast moving traffic, so something
else is going on. Either I'm walking really really fast (unlikely) or they're picking up dust or
they've been set to single flash occassionally, just to keep any passing motorists on their
toes...or...something else (malfunction ?....) Dave.

The triggering mechanism (radar) does many clever things and gives a precise speed automatically.
The photo is not something that is automatically processed. So really, yep.

The recent case where a reflected radar signal gave a car doing 13 mph a speed of something like 56
mph shows that they don't use the photos.

One of my pleasures in life is chasing police cars down the motorway at 80+ mph. Unfortunately, as
soon as the put the blues & twos on, I'm in a sticky position !
