Forget pipes, acquire tubes!
A lot of people are asking for pipes, and for faster people transport. It would be super cool to me for there to be a faster way to get between discovered point A/B and jump pads just don't have the kind of distance/thrust needed (and then you basically always have to have a jetpack to not die on arrival).
Unless the intention is to always have players ride belts like the mighty sandworm, it would be nice to see some kind of transport specifically for players, and I think tubes (a-la Futurama) would be neat.
Vehicles are cool and all, but who has the room to leave huge roads, plus they're way slower than belts.
