Fantastic. While I don't care about cars, Elon Musk getting richer will be good for space exploration.
The space in the solar system alone is literally quadrillions of times the volume of the entire Earth.
Each day we wait to explore the universe, millions of planets effectively cease to exist.
I've not made up my mind about this whole expanding universe thing (whether it's permanent, local, even real) but based on our current understanding it certainly seems that you're right - the world is getting a little bit smaller all the time. Time is of the essence - we need to move fast.
