Modern cars have computer controllers in place to keep emissions under
control and to have the desired mix of performance and fuel
efficiency. In order to do this, it keeps tab on engine conditions and
vehicle speed. They're not black boxes in the sense of being a
fortified data gathering device. They are actually the heart of the
emission control system.

As far as I know the boxes are proprietary systems belonging to the
manufacturer and any data that may remain in the computers after a
crash is not available to
outside agencies.
