| There's a number of people whom make these car Lan transceivers.
| The CAN bus is primarily used by BMW, I think they get their parts from 
Seimens
| but I am not sure.
| 
| I (squared)C is another bus type. I am not sure who uses this.

I2C is used (for example) in computers for cummunication between the power 
supply and the motherboard.

| 
| The point is: there is NO standard for automotive communication busses.

This isn't true.  OBD-II has mandated a standard for auto busses.  It comes 
in a 2 wire and a 3 wire version.  The spec covers both the electrical 
specification, the format of data packets, and what basic information must 
be made available.  Manufacturers are free to add other info and not 
disclose it, but the OBD-II compliant part is public information.
