As the title states I had an idea well more of something that inspired me from Star Trek Voyager, there is an episode titled "Drive" that sees the crew enter into a sub light ship race and I thought man I would love to see a racing line of ships and actual courses spread out through the bubble and perhaps beyond that with a dedicated career path worked in for it somehow. This would just be cool not only visually but if there were some regulations and ways to engineer mods within the specifications of each upcoming event so you could work on your racing ship in between races to bring them up to the next challenge.
