A palm-sized knob instead of a steering wheel, fast "smart brakes" instead of hydraulics: Aumovio and Astemo are proving in Sweden how radically by-wire technology is changing the design of vehicles.

Vehicles are no longer mechanical constructs with a little software, but "software-defined vehicles" (SDV), in which the architecture is rethought from the ground up.
