Re: eCall only activates when there's been an accident
"In a recent murder case in Wales, the evidence against the accused was largely based on data sent from their Land Rover Discovery to LR's HQ."
The data was not sent to LR's HQ or anyone else - data was retrieved from the Event Data Recorder module. These modules store data for analysis after a crash and include parameters such as speed, accelerator and brake pedal positions, G forces, etc. But the data can only be retrieved by physically connecting the module to a computer with the relevant software, via a suitable cable.
