You speak like I only fly a fighter or something. I do trade, and plenty, and I value(d) thrust speed on my traders. I'm bummed that my beloved Behemoth lost not only its forward guns but also it's 200 thrust speed in exchange for +500 cargo. She's less fun to fly and takes one helluva long time to get away from the annoying NPC disruptor spammers at 140 now. She was a nice RP trader for me but now she's pretty much bleh. I flew that ship specifically because she was faster than the bigger ones and never regretted the choice or yearned for a larger ship. And she had a 2500 unit cargo hold.
But if speed is of no value to you then i can see where my proposal wouldn't do much for you.
Unseelie, you can bet a prison liner wasn't made for sight seeing. You also need to consider that in FL there is no faster way to travel than by space ship. On earth we fly in a jet or take an express train to get somewhere we need to go quickly. We hop on an ocean liner when we want a vacation. However 100 years ago we took fast (relatively) liners across the ocean. Their owners prided themselves on the speed of their ships and the number of souls on board.
For passengers, FL is much more like the age of steamships than the age of air travel.
Good luck with your long skinny transports. I hope they become more what they were and less what they are in the future.
