It has been discussed several times and the sense of scale feels off for 3 simple reasons:
1) Acceleration is way too high for ships the size of the ones in Elite, both how ships handle inside space and how they're treated by the game itself during landings, station docking etc is completely off and unrealistic. You can't have a station platform the size of two football fields move 180° in a few seconds. It feels like we're in a f-14 even when we're piloting something the size of the Empire state building.
2) Cockpits are too big compared to the actual pilot seat. Ship is almost double the size of what it should be to cozily fit current cmdr proportions. Once you notice it you can't go back, if you look at your cmdr with the cockpit angle in camera mode it looks almost like an action figure sitting on a bus driver seat.
3) Very low texture resolution of basically everything, planets, stations, ships, ruines, interiors, cockpits, you name it.
This^ (and i play it in VR)
Cockipts are unreasonably big, no manufacturer would build such cockpits looking from engineering and economical point of view.
However not all ships have that problem given that our avatars live in their ships so some comfort is needed but i guess bridge doesn't come under that point since it is a workplace rather than pilot's living room.
For example Phyton is quite good while Conda or ASP has no sense at all.
In aviation designing special study is used (programs are written for it) to give user enough freedom of movement, accesibility, usability, comfort and field of view while keeping it economical and performance wise lighter.
Another problem is acceleration and speed when approaching objects such as stations as well it's low resolution and surface details (understandable as it would require a lot of work and would cost us performance).
For me even planets are off scale again for landable ones there is no atmosphere therefore no air resistance so speed and acceleration kills it scale feel.
While gas giants, atmo planets and stars have distance approach limit which kills it scale too.
I guess if landable atmo planets ever come it could change making our ships more difficult and slower to land on.
Also atmosphere thickness when entering it will give much better feel of scale and planet's size.
In SC landing on atmo planet takes time and that's what gives feel of it's size. (Don't know for the rest of the planets since i tried it only once).
