All vehicles for at least the last 25 years have had CANbus architecture installed - the system used to ensure that ECU's, microprocessors and sensors can all communicate with each other.
It is one of the most important developments since the silicon chip. CANbus architecture is used in a myriad of machines, not just cars, trucks and aeroplanes.
We would never have the integrated functionality of modern electronics without the CANbus system.

ECU's, microprocessors and sensors in automotive applications are reasonably reliable today. The greatest single failings of electronics in automotive applications today is inadequate protection of harnesses and connectors, and major contaminants such as water, dust, chemicals from soil and air getting into these areas. Damage whilst in use, and faulty assembly, are the other areas that produce faults.
Electronics are complex on IC-engined equipment, because IC engines in themselves are complex devices, with many demands for rapidly changing inputs and controls. Electric motors are much simpler, they only require input power and a method of controlling it. Regenerative braking or battery regeneration under deceleration is a huge hidden asset of electric motive power.
Vast amounts of energy are wasted by IC engines - in wasted heat, in unnecessary fuel burnt just to keep things ticking over. An electric motor only draws the level of current and produces the power output required for any particular time and level of power demand. Once a vehicle is rolling, only a tiny amount of power is needed to keep it rolling. An IC engine produces far more power than needed, under light load.
Aircraft are a somewhat different kettle of fish as major power draw is needed to take off and climb to the selected flight level. But even in level flight, aircraft demand more power to keep up the desired speed, as aerodynamic drag is a massive drawback to cruising through the sky.
So, electric aircraft will always be behind the 8-ball, as compared to road vehicles, and until major gains are made in battery lightness and energy density, pure electric aircraft will never ever be competitive for anything more than short hops. On that basis, I see hybrid power as being more likely to be the power source for longer-haul electric aircraft in the future.
