We really love all of the SpaceX visuals for the first city on Mars, but we see that they've have forgotten the most important thing: A Velosolutions Pump Track! We assume that even the people on Mars will want to have some fun and stay healthy!
With gravity being at only 38% of earth's, we can probably supersize the track!? We’ll figure it out.
Who is willing to help us during construction? Free commute. With 62% less gravity, supersized track. What tricks are you going to pull with that?
