The question How well could the Tesla Cybertruck drive on Mars? received five close votes and was put on hold, then re-opened, and now currently has four more close votes, for a total of nine, most or all for "primarily opinion-based".
The question has received two good quality, well-received and fact-based answers that convey plenty of engineering concepts relevant to the challenges that vehicles on Mars face.
The votes seem misguided to me, since obviously the question attracts answers that are primarily based on engineering principles. And yet nine users felt compelled to close it!
What might it be that is triggering all of these close votes? Is it (the apparently unfounded) fear that the community can't handle the question? "Better close this before someone posts an opinion" Is it simply the words "How well..." that triggers autonomic reflexive closing? Or is something more subtle going on?
