Sure, but you're building on a dramatically smaller piece of land so your total overall parking requirement doesn't change. 4 stories of 100,000sqft vs 40 stories of 10,000sqft hold the same number of workers, but the tower only uses 1/10th of the footprint.
The fun part is when you start building a lot of these towers very close to each other and then all of a sudden your parking needs plummet because transit is way more effective.
It's not going to happen in the Valley though, they're stuck with gross office parks.
