Depending on which road you drive on, be careful to not get a ticket for driving too slow. 
The French need to cash in all the taxes they can get. 
Eric You never actually own a Defender. You merely look after it for the next generation. http://youtu.be/yVRlSsJwD0o https://youtu.be/vmPr3oTHndg https://www.youtube.com/watch?v=_GtzTT9Pdl0 https://www.youtube.com/watch?v=ABqKPz28e6A https://www.youtube.com/watch?v=rLZ49Jce_n0 https://www.youtube.com/watch?v=XvAsz_ilQYU https://www.youtube.com/watch?v=K8tMHiX9lSw https://m.youtube.com/watch?v=dxwjPuHIV7I https://vimeo.com/201482507 https://www.youtube.com/watch?v=ZSixqL0iyHw |

Earlier this year a chap on another forum I participate in received a ticket for doing 119 mph past a speed camera in a 40 limit. In a Defender 110 !
Whilst I am sure that there are 110s on this forum that could potentially do that, this is apparently a bog standard work truck, complete with the factory speed limiter. Naturally he queried it with the issuing authority (I suspect along the lines of "you're having a laugh") and received an apology and the explanation was that there was a camera malfunction. All of which made me think that it was a good thing that the malfunction caused his speed to be reported as unbelivably high; he'd have had far more trouble if it had incirrectly recorded him as travelling at say 50mph. |

It is a great shame that LR, in their wisdom, only allowed the selection of one of three presets for tyre size. It would not have been hard to set the ECU up to allow any tyre size to be entered, so those of us with other sizes could easily calibrate our speedo. As it happens, I have checked mine with a Home Office approved timing device against Dorset Police's measured calibration markers since fitting 255/85 KM2s, and it is spot on across the board. On 7.50s it predictably over-read across the board. Incidentally legislation does not require that the speedo shows a higher speed than actual. Legislation requires that a speedometer does not under-read at all (it must never indicate a lower speed that is actually happening) and must be accurate to 10% of actual speed. So it must have an accuracy of -0%, +10%. It would be inordinately expensive to make a speedo which was guarenteed not to underead, since typically a quality speedo, at least one of traditional construction, is accurate to +/-5%, so the conventional solution is to make a speedo which is designed to under-read by 5% and has +/-5% accuracy, since this will result in the desired legal -0% +10% end product. With modern technology however there is really no excuse for not having a true calibrated speedo. |

Using a Scangauge for more accurate speed display - compares favorably with Garmin GPS readings. Except for being more accurate - the digital display also easier on the eye than the analog OEM gauge. On a previous vehicle - changing to different circumference tyres and rims got the speedo spot on but the odometer went out of range again - with effects on mileage before going for service and calculating fuel consumption (manually) again.

Tyre wear and pressures will affect the calibration. On my L322 satnav there was an option for wheel calibration, which you were supposed to run everytime you fitted a new set of tyres. Nearly worn out tyres will be slightly smaller (and therefore turn faster to cover a given distance) than brand new ones. I'm not sure a Defender could be described as "Modern Technology" mind you. 
But i'd agree on a modern car, especially one fitted with built in satnav it would be realitively easy to have an automatically calibrating 99% accurate one. |
