Yeah but the brain gets more excited going from 0 to 10mph on a self built skateboard than from mach1 to mach2 on the Concorde, because you are in the exciting part of the S-curve.

Also because skateboard you singlehandedly crafted and it's yours, Concorde you need a million people give or take to build and billions of man hours and you get to rent 1/160th of it for about 3 hours. And those 3 hours cost some serious ass kissing to acquire.
