At a seminar a while ago electronic brakes were discussed as part of the growing need for 42 volt electrical systems. The smirks and chuckles filled the room untill the instructor pointed out how similar doubt had accompanied the onset of hydraulic brakes in 1940 (or so). After all can you imagine the lack of confidence one would feel going from the positive action of cables to the use of fluids to accomplish the same thing.
