You are not looking at this right. Elite is a game of being a real live, normal, every day person, trying to make a living for themselves in the massive galaxy in which we all live. It is not a game about being a hero, a warrior, a princess or a magic fruit. People are substantially boring. Life is basically boring. We do pretty much the same thing all the time. What makes life interesting is the goals and trials we set ourselves, not how powerful the political party we support has become or how our group of friends "own" the street they live in. So with Elite, you have to set your own goals and succeed or fail in them. Frontier seem to be trying to make goals for people but it won't work and it can't work. Perhaps they too have forgotten what has made Elite last forty years.
Your exploration example is a perfect example of why some people find the game boring because they just don't get it, or don't want a game of life. Do you think Shackleton was brimming with excitement as he dragged a sledge, mile after mile across vast swathes of endless ice that all looked the same. Do you think he hummed with anticipation that the temperature might rise above -20 for five minutes. No, he trudged towards the pole, step by plodding step with back breaking endurance and probably constantly wishing he was home playing Elite instead. He didn't even make it. Scott may have entertained himself with lots of science before he actually did any exploring but, in the end, he did the same as Shackleton except he endeared himself to us all by eating a horse and writing a cool letter as he died.
The explorers of Elite are doing exactly that but in game form. The endurance required to get to The Abyss, let alone pick and plot a route through it and then, perhaps, find a bridge of scoopables between galactic arms, to report back to other explorers, perhaps having it named after them, is EXACTLY the right spirit for exploration. The honk, scan mechanic is irrelevant and making it "more interesting" will, in fact destroy it and make it far more boring and repetative
Much the same could be said of the prospectors of old, panning for gold or the pirates on the high seas and even, would you believe it, your modern combat soldier. In that, Elite has it perfect with long stretches of absolutely nothing and suddenly, intense and uncompromising action.
Perhaps your trading screen would be good and perhaps more unexpected things happening from time to time would help but Elite should always be a reflection of life, not a reflection of what many people wish it were.
Sorry to rant at your post

It was one of several.
