Estimating your delivery date is a combination of:
What is your reservation number?
What percentage of reservation holders do you think convert to purchase?
How many Apteras/month do you think is "full production"?
I'm hoping someone more knowledgeable than I am can shed light on questions 2 and 3. (In the Denver EV video Nathan Armstrong estimated July 2022 for full production.)
I think the full production number of 10k per year would be per factory location. There were mentions of possible factory locations, a second in the US, Europe and I would think somewhere around China eventually, or China will copy it. Only time will tell.
