Why would someone do a mass edit of the files? surely the use of something like DigitalEPO would be a lot simpler and easier
Digital EPO which is used to increase the speed of a ride. That is helpful in the context of an accident. Yes officer, I used this cheating barsteward app to make me look 20% faster as I rear-ended the motorcyclist.Why would someone do a mass edit of the files? surely the use of something like DigitalEPO would be a lot simpler and easier
And how would you account for, acceleration and deceleration at every single point where the data is recorded? You didn't start your journey at x speed and continue that way for all of it.
So. Too big to edit immediately,and easily prior to an accident.(and that's just one data field) I think so.
I don't disagree it can be done. But I can't see how it can be done convincingly/easily and quickly after an accident. Much to say,if you wanted to appear innocent by not being there(a simple delete of the log file?), moving slower or being stationary - it would be overall difficult.TBH, I just used the example of a car speeding as a convenience for demonstrating how easily the XML could be modified en masse (in this case, to remove evidence of a car exceeding the speed limit at some point during its journey). Work out max speed, remove some factor X to make sure it never goes over the limit, and you were never speeding (unless they work through the trig of your XYZ and timestamps and compare that with the modified speed field--now *that* would take some work.

< Can't think of anything clever>(Editing 'prior to an accident' wouldn't make much sense, would it? )
Well you know what they say about these helmet camera users looking for trouble and staging events to get their 30secs of youtube fame(Editing 'prior to an accident' wouldn't make much sense, would it? )
I think that is the case the .gpx file is too long and complicated to edit for most folk but the possibility remains and some 'clever' lawyer would use that, so even if it was 100% accurate I don't think it could be used
That does get interesting. Especially if the vehicle tracker shows it to be somewhere it shouldn't, perhaps suggesting that the driver (who would be aware of the trackers existence) was doing a bit of extra curricular work.If a driver's company is using a real time tracking system it would need to prove that the vehicle was being tracked, and not the driver, r alternatively obtain consent
