Dont compare games to real life situations, games are meant to be fun and engaging, safety features in cars are meant to keep you alive and safe, once you start comparing it to real life it soon gets to a point where it's entirely silly. The planetary departure mechanic in ED is entirely meant to stop your ship being targeted while you were away from the ship. If it was only present when you had the module installed then players who didn't install a docking module to save space for other modules, or because they preferred docking manually, would be at a big disadvantage to other players whenever they landed on a planet. It would basically force everyone to fit a docking module whether they wanted one or not, which is not what you want in a game.
1) My answer was in reference to the comparison with the Audi who bought the guy above
2) If the modules were integrated no one forces you to keep the option active. Even now, by mounting these modules, you can choose to turn off/on the auto dock or supercruise assist function from the right panel. As can be done with the orbital lines of planets, for example. I just can't understand the problem.
3) ED is a game that also tends to be simulative, it is based in a real galaxy with many real elements and others, of course, invented. Moreover, as already mentioned above, already over the years many functions of the ship or mechanics of the game have been changed, I do not see anything so apocalyptic in all this.
4) Justifying the presence of the automatic functions of the ship only for those who land and do not want to risk the ship does not seem equally right to me then. If you want to make sure no one destroys your ship when you leave then you organize yourself first and install the module, otherwise you risk it. The main component of ED is risk, on the other hand.
5) The AI issue you mentioned works up to a point, maybe at the level of lore, but if it were as you say then the discussion wouldn't even be there because such modules wouldn't really exist in the game
6) It is undeniable that Elite would have all the potential to be the perfect game as an idea, but at the same time, in addition to all the obvious optimization problems that exist since the release of the game, it is evident that it has many problems of poorly thought mechanics that users propose suggestions or put the patches to fix. Remember Inara or EDSM? When did Frontier not even allow data synchronization? Even today, for Frontier, a player should turn totally randomly to find modules, ships, weapons, suits or whatever ... Maybe there are those who play Elite every day 10 hours a day and it is also good for them like this, but there are also those who play Elite a few hours a month and the game makes you throw them away without having done anything. What I propose now seems to me a banality that does not change anything to the game, that takes nothing away from anyone, but vice versa, in my opinion, it meets everyone equally.
