Such attempts at persuasion, in my opinion, cannot work in a forum, as one would need much more background knowledge about the person to be convinced, who sometimes does not want to disclose this publicly.
I would not just present my opinion or conviction to anyone arbitrarily, but exactly to the person who, for example, asks about it here in the forum or participates in this discussion. Whether this then leads to concrete results I cannot say either, but at least I hope that it leads to food for thought or inspiring ideas. Often the path does indeed go through many and long curves until one arrives at the self-desired goal. My notes in the forum therefore go exactly in that direction, as you write, namely to outline the maximum context of a situation, which, for example, already begins when filling out the questionnaire. All of this, the BP, the age, income, children, the individual life, etc., is exactly the necessary context to be able to give the best possible helpful answer or opinion. If someone is reluctant to show personal background, then a rather limited answer quality can be expected; therefore, ultimately everyone decides for themselves the degree of help possible for him/her. As I have already written elsewhere, I have increasingly noticed such preset attitudes and closedness in the forum. But that does not simultaneously mean for me that I would have to adapt to this change. I still mention personal details or openly engage in personal contact with members, as I also always take something away from it myself in the same way.
Your example of e-car is perfect for that. It (not yet) fits for everyone. And not everyone then wants to reveal all thoughts and facts about it.
A (e-)car never fits everyone; my cousin, for example, will never want to drive a car at all, my nephew has three diesels standing in the garage. Nevertheless, I am interested in their backgrounds and I then mention mine in conversation for our two e-cars; both can exist side by side and in the respective context for the individual also be the better option. If I participate seriously in a knowledge forum, I should be prepared to also put the context of my situation or my motives up for discussion. Otherwise, I would ask myself what the motive for participating in the forum is, because merely by using the internet among other things, I have already disclosed my privacy to the maximum, whether I like it or not.

Therefore, it unfortunately often degenerates into proselytizing.
That may often be the case, but as always it is also up to each individual to improve this coexistence. For that, I am gladly a very committed optimist despite considerable hardships in my life. In principle, we may not be that far apart and even if we were, that would not be a problem. My earlier life with a large sliding door was neither better nor worse than life now without one; here too, several things are possible.
