Variable max travel speed
The max speed of 100 m/s has continuously annoyed me, especially when leaving the atmosphere. Inspired by Elite: Dangerous, which doesn't do exactly this, but something with almost the same effect, I thought about increasing the max speed dynamically depending on the object's distance and speed difference compared to other simulated objects.
Using this approach, ships and players would be able to hover around their main ship (especially fitting with the new relative damping feature) without causing a max speed decrease. Should the ship come near a voxel structure or another simulated object, their max speeds would be reduced gradually to around the current limit of 100 m/s.
Being a game dev myself, I'm very keen (no pun intended) on hearing your response. I could imagine checking relative distances between every nearby object continuous has a potential performance implication.
