Do cars still need cable harnesses?

Cable harness, also known as wiring looms, transmit signals or electrical power for automobiles

Although they’re hidden away behind trim and under carpets, traditional, copper-based wiring looms still take up space and add weight. In future they could be replaced by wafer-thin and bendable printed electronic circuits, currently used in curved televisions. These could be ‘printed’ into the car’s body panels and provide a lightweight, space-saving alternative to traditional wiring for instruments, switches, lighting, heating and screens. The tech is being investigated by Jaguar Land Rover in the UK.
