I'm not OP, I'm the lad who can't even locate his box. I've traced the OBD2 back and there doesn't seem to be anything there.
I speed regularly but still get 100/100 for the speed rating, so I'm not sure exactly how it reports it. When I cancel this insurance, I'll rip the box off and have a look -- I'm an electronic engineer so hopefully I'll be able to deduce something. This won't be for a while though. As one of you two already said, to constantly poll and report a full dataset would use an incredible amount of data. I don't imagine there would be any way to detect if the driver is speeding on the chip -- having a fully fledged GPS would be costly, computationally expensive and unreliable, as I imagine all of the reports are checked against a constantly updated central map. To work out if the driver is speeding, I reckon it would be necessary to send back location and speed data at a fair rate, which I don't think is done. I do, however, get pretty much random acceleration and braking reports, and that is something that the accelerometer/gyro could log and send back in batches.
Pic attached is my scores for last month. I'll probably solve it as a set of simultaneous equations to figure out the weighting and what they value more.
