The IT in a car is even worse a black-box then most closed-source devices. The whole internal network is a black-box, not just devices. Nothing forces car-manufacturors to use standards for informantion exchnage, or even TCP/IP.<p>I am waiting for the first Open Source car on the commercial market. One where not only the software and "drivers"(no pun intended) are freely available, but one that uses standards to communicate, internally and externally.
