wjr writes: Many cars these days contain black boxes that record information (speed, accelerator position, etc) and can preserve information in the case of an accident. Ford and Chrysler say that they use "open systems" so anyone can read out the data; General Motors has licensed Bosch to produce a device capable of reading its cars' black boxes. On the other hand, Toyota has only a single laptop in the US capable of reading its cars' black boxes, and generally won't allow the data to be read without a court order. Honda seems to have a similar policy. This is emerging as an issue in the investigation into unintended acceleration.
