Is 4th Quarter 2021 a realistic delivery date for the Cybertruck?

I spend about 7 years at a GM car plant in General Assembly, I was not an Industrial Engineer nor did I do line balancing, but as I recall, if a process took more that the allotted time, they would have multiple stations and tools dedicated to that process. So if you had a process (i.e. windshield installation) that took 1 min 30 sec, you would have 2 separate tools in two different work stations installing that part. Thus still making the 53 sec window allowed, just taking up more floor space and was more expensive because you had to have multiple operators and multiple tools.

If I remember right they were doing this for cockpit install, fluid fill, and maybe others. I do remember multiple glass install stations, but I thought maybe they were for front and rear.

Just my thoughts. Not from an expert.
You are 100% correct. On the line in Shreveport, we had a cross-body harness station that took more than 52 seconds so we had two teams that would leapfrog every other vehicle. My point was that limiting the number of processes does not mean that vehicle production speed for that line gets any faster. In fact, the opposite is quite often true. Instead of one station that takes 52 seconds to fasten 8 fasteners, you could have 8 stations that all put in one fastener every 10 seconds which would increase the throughput of that process by 500%... However, that adds cost which is what they are trying to avoid like you said.

First of all why does he need a completely built factory to start producing vehicles. I’m trivialIzing this but when we start downloading a large file We can start playing certain parts after a certain percentage.

I don’t think that is true (re the file download), but all of the Tesla properties are being added on to piecemeal, so they know they can build up a portion and begin operations. I think the question you are trying to answer is whether the CT portions of the factory can be operational while they build out the rest of it. Perhaps, but if the time in between is short enough they probably won’t do it due to logistical complexity.

If Tesla is known For anything , it’s that they are good at solving complex problems.

I wasn’t trying to say otherwise. I was saying it might not be necessary. They are also smart enough to know when or when Not to solve such problems.
