I suspect there's substantial thought. We here seem to be the ones not giving it much thought. For example, one of us thought about only a 2-dimensional parking lot to eat up much of the space. The math appeared right but approx halve the space by adding only one layer of parking above or below and about quarter it with 4 levels of parking.
Besides a parking tower, they could build underground parking so that the entire surface is available for working space and/or have multiple floors of working space and multiple floors of above & below ground parking leaving most of the land free as greenspace.
I suspect people who can flesh out the intricacies of building Macs, iPhones, iPads etc have the brainpower to put some good planning into much simpler construction of office + parking space... and/or are smart enough to hire teams of people who specialize in such creations.
