Just looking at past sales numbers and ignoring these transition is insane.
Transitioning millions of vehicles to EV is an incredibly hard task and has massive cost and massive constraints do to battery, battery materials and chip availability.
I'm not gone say Tesla is not 'overvalued' but just saying F-150 sells a lot therefore Tesla is overvalued is bad argument.
Ford's 2020 Q4 report [0] indicates a sales rate of ~2M cars / yr. The entire Ford truck brand sold around 1.1 M trucks [0] that year (2020) and 1.2 the year before (2019). Fordauthority.com (who may or may not be authoritative...) says that Ford is/was running slightly worse sales this year than last year [1]. However I don't think Ford has published their numbers for 2021 yet.
Personal Opinion: Given Tesla's ramp of ~70%/yr, is it not absurd to think that Tesla will pass Ford's truck sales numbers within the next year and all of Ford's sales numbers within the next 2-3 years. (This is assuming lack of innovation on Ford's part. If Ford innovates with e-trucks then it will probably take a lot longer for Tesla to catch up)

Ford is also years behind in battery and fsd tech. That being said, they need to match / best expectations handily to retain these valuations
