I was flicking through a handbook of another car last night (yes I know sad) and on a section regarding the engine management system it said that in the event of a collision or near collision a Jaguar dealer could download information such as how fast you were going, if you and/or passengers were wearing seatbelts, if you were applying brakes, if you were applying accelerator etc etc. It said they needed the owners permission to gather the info unless requested by a law enforcement officer.
I didn't realise they could do all that! Is this a common thing on modern cars now?
