Moving offices outside of the downtown doesn't really help. The only visible benefit is less load on the city center (often tourist and historical destination).

It simple 2D geometry - if you live 1x from the office your commute is 20 minutes, if you live 2x from the office, your commute is 50 minutes, 3x from the office - 90 minutes commute, and so on. If you move the main cluster of the offices outside of the city border, then the commute time would change for people, for some it will decrease, for some it will increase. There would be exactly the same percentage of people living 1x, 2x, 3x etc. from the office, just the people would be shuffled between the quartiles.
