Any Surrey traffic cops lurking 1093

Well, true to an extent. The DIP switches are normally 'protected' by 'security' stickers. There are multiple techniques of by-pbutting them. On the other hand, fiddling about with a normally inaccessable part of the wiring loom is less likely to be detected.

Oops - sorry, I was wrong. Apologies.

And similar methods.

Not sure what you mean by 'pretty much'. in the study I've referred to elsewhere in this thread regard to tachograph fraud and tampering:

"However, the consensus of informed people in the UK is that maybe 5-10% of drivers are persistent offenders and about half offend occasionally. The persistent offenders tend to be buttociated with cer- tain operators, some 20-40% of whose vehicles turn out to have signs of past tampering when examined closely at inspection stations. These signs include seal defects, calibration faults and suspiciously loose wiring 34. The significance of this is that well funded attempts to defeat future tamper proofing systems can be anticipated; one operator with over a dozen tachograph convictions has over 500 trucks.

34 `A Report on the Fitment of Tachograph Interrup- tors', 10-8-95, Vehicle Inspectorate, Wighill Lane, Walton, Wetherby, West Yorkshire"

Note the operator with over 500 trucks(!). To be fair, the "paper reports research funded by the Department of the Environment, Transport and the Regions during 1997-98", so things may have improved since then, although the author of the paper didn't seem too optimistic about it.
