I am unsure if the data monitoring on LR vehicles is automatically collected, given it seemed to be optional via a supplied code to be entered to enable tracking to begin ...?
Oh, I'd have thought the data is all collected as a matter of course. Owners have an option to buy into the tracking system to be able to access that data (or, presumably, to file a GDPR request every month if they would rather go through the tedium of that process than pay the subscription fee). Plod, armed with a warrant, can get the data whether the subject has subscribed or not.
It's all getting very high tech, isn't it..?
It's remarkable that they have the data, but don't appear to use it commercially. I may be wrong, but isn't it all about permissions when you're loaded with things like this..? The information on movements will rely upon satellites and the usual GPS points, and it's my understanding that currently, the accuracy isn't sufficient to beyond 'Reasonable Doubt'. Again, I may be wrong on that one. Either way, investigating a murder has certainly moved on in Midsummer village..!
On a separate note, I read somewhere that the insurance 'black box' initiative for newly qualified drivers has been proven to be so faulty it's almost fraudulent.
Speed limiting however, is a much different matter.. Over speeding could even be handled away from the Police then. DVLA for instance.. And they NEVER make mistakes, do they..?
Accuracy with a "straight" GPS signal in the UK will pinpoint a vehicle to within about a metre, so plenty accurate enough to establish the whereabouts of a car at a particular time, down to which parking bay it is in in a car park, or which side of a driveway it's parked, for example.
The only issues with accuracy of GPS come when looking to get autonomous vehicles to park close to the edge of a road (with no painted line or easily defined kerb, otherwise of course it would use a camera or lidar scanner to sort it out). Using differential GPS, which requires some seriously complex mathematics to detect phase differences in the carrier waves from a minimum of two GPS satellites, it's quite possible to get centimetre-level accuracy for a GPS receiver on the ground anywhere in the world. That's a bit expensive yet for mass production in passenger cars, but is already in place in farm machinery, autonomous heavy equipment in mining, and increasingly in high-end drones used for airborne survey and mapping applications.
