A vehicle bus is a specialized internal communications network that interconnects components inside a vehicle (e.g. automobile, bus, train, industrial or agricultural vehicle, ship, or aircraft). Special requirements for vehicle control such as assurance of message delivery, assured non-conflicting messages, assured time of delivery as well as low cost, EMF noise resilience, redundant routing and other characteristics mandate the use of less common networking protocols. Protocols include Controller Area Network (CAN), Local Interconnect Network (LIN) and others. Conventional computer networking technologies (such as Ethernet and TCP/IP) are rarely used.
All cars sold in the United States since 1996 are required to have an On-Board Diagnostics connector, for access to the car's electronic controllers.

“If you would learn to write, ‘t is in the street you must learn it. Both for the vehicle and for the aims of fine arts you must frequent the public square. The people, and not the college, is the writer’s home.”

“In the dime stores and bus stations,
People talk of situations,
Read books, repeat quotations,
Draw conclusions on the wall.”
