Wussies? They're not all obvious sadly. Most cameras are now supposed to be displayed in a prominent position and painted in bright colours but this certainly isn't always the case.

I know of several cameras placed directly behind road signs or large trees so that they're not visible until the last minute. Motorists unaware of these cameras then slam on the brakes creating a potential hazard.

Anyway, the debate over speeding is bound to rage on for quite some time. Back OT, I've found a few more sites with suitable databases of camera locations. There are also individual sites for each of the major police forces.

PDA based speed camera warning - might be useful to reverse engineer the file format, and use the database on the empeg (£50 p/y subscription):

Another text based gatso database, although with some OS references:

A DB from the association of british drivers, although it is no longer being kept upto date.
http://www.abd.org.uk/cameras/map.htm

Lots of other links on that site too, including this one:

Oh, and here's a link to backup the "speed cameras not on dangerous roads" argument:

Anyone have a current link to download gpsapp?
