Deepsquat and Hirev: In neither of those two stories is there mention of data from a black box. If there were black boxes in the cars involved, the particular technical data collected would be irrefutable, and the cause and fault of the accident would be better known.
For those who say manufacturers would build a case against you for a pattern of speeding, in court, previous behavior isn't proof of anything and would likely be inadmissible (although I do see a problem of a jury ignoring it). Perhaps a legal expert could chime in?
I do agree that the manufacturers will try to use whatever they can against you, but if the data belongs to you, the owner, then wouldn't you prefer to have this data than not?
