You’ve never worked with automated equipment.
I have worked with automated equipment, and I have worked with computers all my life. While nothing designed by humans is perfect, a lot of equipment can be made to remove the failures of human-factors, and we do end up with a lot fewer problems and better situations all-around.
Who among humans can say that he/she can do things more precisely and faster than a robot or a computer? If automated vehicles remove just 1% of accidents from our roads, our lives will have been improved tremendously. But, the promise is for removal of 100% or human failure from our roads; I’m willing to accept just 50% improvement in lowering in the number of accidents and deaths.
