This is a bad analogy, because air travel is a passive occupation, so it is desirable to make it as short as possible. Plotting out your own route around barriers and hazards and planning resource consumption is interesting. Long range exploration is a challenge, and jump range inflation negates it, or makes it an artificial challenge by limiting yourself, like walking to Spain on your knees.
Imagine if an explorer, seeing combat as a nuisance in the same way you describe travel, came along and said that there is no challenge in fighting NPCs with an engineered ship and system authority do most of the work anyway, so we should be able to insta-gib any NPC with something Ed's godmode tools if we want to get out of an engagement.
Well, the issue is that there are no barriers nor hazards in the ED galaxy beyond very rare close contact binaries and oddball places like the Rift or Rho Cas.
Which means that exploration is akin to air travel and people find it desirable to make it as short as possible.
If jumping into an unknown system was dangerous, and more so if you jump a long distance into it, then the whole perspective is changed. As for now, getting to beagle point is
easier than driving on the motorway for the same number of hours. I.e. not that hard.
Imagine the following : explorers can jump 150 lyr (extreme X-annie + J3 level). Cool. Now, imagine that if you fire that toward anything unknown, you had a 99% chance of
putting the ship in danger. Like faceplanting into a neutron star lower than the drop zone, or crazy stuff like exiting above a 3G world with the ship rebooting. Would you use it for fast travel ?
Now, if said risk where much reduced upon the system being explored at least once, and even more if you know it, and completly removed with nav beacons, we would start to have something interesting.
Especially if players could lay and fabricate nav beacons. You could also imagine FSD probes to send ahead to gather more informations and lower the risks.
That is, actual exploration and pathfinding gameplay.
^^ the Brown dwarf desert field. Nice. Those should be rather safe IMO. Trade off : go to the safer Brown dawrves and miss on fuel, or go easy with refuelling but higher risk ?
And yeah, "crunchy galactic terrain" is exactly what we need.
Also, what if upon jumping, when your jump trajectory is passing close* to
ahem massive objects they could :
1) Pull you out. Though you where to exit 50lyr away near a nice G star ? Nope, this is the triple B star system at the 31 lyr mark. And they are so damn hot...
2) Sling you : you though you would exit near a nice safe Brown dwarf 60 lyr away, but there is the issue of this 15 Msol BH just near your trajectory. You suffer a massive
FSD overcharge, you faceplant 150 lyr too far and 30° off course into a neutron star with a destroyed FSD and a ship roasting...
*Note : that would happen a lot in the core. Which would make the core a damn dangerous place...
