Standardized Data Collection Methods already exist
One of the ASTM Standards Committees on which I serve is Committee E30 on Forensic Sciences. (The committee's alphanumberic disignation is a funny coincidence :angel: .)
Anyway, among the documents over which the committee has jurisdiction, is one titled "Practice for the Investigation of non-Volatile Memory Data in Evidentiary Vehicle Control Units"
This standard is clearly designed for use in situations in which there is litigation, and it's hard to imagine that in those circumstances one will be able to prohibit a subpoena of the data. The ASTM document, of course, only discusses the collection and preservation of the data, not legal issues.
When I was reviewing it, I did wonder whether I had more 'rights' to the use of this information as a 'buyer' of my car than people who lease their vehicles do. Specifically, is leasing a form of ownership? Rental? Does the answer vary by state?
Further, when the title to my car is held by the bank if/until I pay off any loan I may have, might they have a right/authority to access the data? Might the insurance company if they have clauses denying coverage under 'demonstrations of speed' or other exclusions.
I would bet that rental agreements for trucks and cars will grant the rental agency to investigate accidents and whether the driver was speeding, racing, screwing around, etc.
It's pretty easy to imagine the slippery slope of commercial vehicles being targeted for this technology, then dealerships, rental car agencies, and insurance companies taking it 'mainstream' to passenger vehicles. Or,.... tell my libertarian ears I'm wrong. :dunno:
