It is not airplanes that I have issues with, since they are well maintained. I only have an issue with this thingy because if it goes into production it will be owned by blockheads who don't know what the word maintenance means. And when one of the gyros fails it is going to cause unavoidable wrecks. I am also leery of the steer by wire idea, seems like a good way to cause accidents. The vehicles that travel our roads and highways are, on average, not very well maintained by their owners. So why would anyone think that a vehicle that needs an electronic device to remain upright or to stay in its lane would be a good idea.
