This all comes back to profitable work generation. MUCH of science just isn't profitable, you're usually doing something that simply shows that something ISN'T possible. This, to the economy, was a worthless result. The only value was to stop other's from also spending money on that same worthless result. That's fundamentally why science doesn't pay well.
The gravity and forces we're talking about are tiny. The craft hit the ground moving slower than 1 m/s and then bounced up over 1km before landing again. The forces involved with something moving that slowly and stopping are minuscule.
You should jump to using Homebrew. It's superior in most ways. I'd used MacPorts and Fink before Homebrew came about and I never much liked either. Homebrew is as simple as it can be and is really good at detecting conflicts which MacPorts and Fink were terrible at.
Not a Tesla owner, but I believe it prompts. Lots of owners were not installing a specific update at one point that contained a feature they disliked. Not sure exactly how the "blocking" of the update happens though.
You just got your first car and you're talking like you're 50 years old... What's the world come to. Having a large screen satnav is a lot better than using my iPhone (which I do normally).
