If we may misquote Billy Joel here, we may be wrong and you may be right. Either new or old fleet automation apparently is very expensive. What appears to remain unaddressed is the practicality of trying to "upgrade" an existing fleet that may be replaced (sooner or later) and having to repeat the process for a new fleet (if one is ever purchased). Particularly in light of the time and duplicative money that will be spent to do this twice. Unless, of course, no new fleet is ever going to be made/purchased. We could "upgrade" a horse-drawn buggy by adding a gasoline engine. That, however, does not make it equivalent to a vehicle designed to be an automobile, and may present unanticipated problems (reliability, functionality, etc). Your posts appear to support automation, and in that sense, we are in agreement with you. We also find your recitation of the need for automation as soon as possible to be well founded and we agree. We are, nonetheless, less convinced and skeptical of the suitability of the current fleet to support this "upgrade", especially in light of the problems encountered to date.
