What planetary mechanics will force us to use ground vehicles instead of flying a ship?

Obviously what we want, and I think that's also aligned with the plan for the tech itself, is that weather, especially extreme weather conditions, will affect the ship and prevent the player from flying through very extreme storms and stuff like that. And we could definitely see this [preventing] flying and needing to use ground vehicles more in certain areas or maybe on entire planets.

As weather continues to be developed, with some of these less aerodynamic ships, you may have more and more trouble reaching the ground safely in some conditions.
