The cost of copper will reach an incredible peak  when more electrical vehicles  are sold. Therefore copper is to be avoided as much as possible because of the high costs and weight. Heavy  and complicated cable harnesses will be the past. Autonomous components whenever possible, must be controlled with a bus system, which is monitored on one control panel in the direct view of the driver i.e on the wind screen.  That system  is combined with the joy stick, which is comanding all driving like in the new generation of Airbus. As each wheel is housing its own motor (wheel hub drive), it serves acceleration and /or braking individually for highest maneuverability.The rate  of acceleration/braking is given by the motor performance. That gives no chance for rapid overtaking, but hovering through heavy traffic jam. The control of each wheel  according its  performance characteristic gives us the  chance to avoid mechanical gears. The vehicle will not contain any gearbox.

An emergency hand brake system must be mechanical in case of  loss of energy or system break down.

All electronic devices must serve the ultimate goal : saving  energy.
