I can see that EVs may need fewer sensors (or fewer types of sensors, anyway) because of not having to deal with hot gases and flammable liquids. But fewer computing elements, not so much. A battery pack may be made up of 20 or more modules that each have their own charge management logic, and there are battery heating and cooling systems that need controlling. Most systems are the same in ICEVs and EVs - cabin control, entertainment, steering, transmission, throttle and brakes, suspension, lights, safety systems, and so on. To me, the difference doesn't seem very large.
