You are putting a whole lot of faith in things which are manmade, thus susceptible to failure. It is a given.
Plus, the electronic dipstick system has to cost more than a straight metal stick with a couple of markings on it. Car manufacturers worry about costs of even very small changes, so I've read. I remember reading about Ford having to make a change in the Mustang firewall sheet metal years ago (unwanted vibration or something like that), and being upset that the fix cost $.50 per car.
