It's nice not to be finding out now, but I wonder if we could estimate a city killer's track well enough to make it worthwhile to evacuate a major city like Mumbai, and if it could be done if needed. And how certain we would have to be to justify an evacuation that would itself be deadly. I'm glad it wouldn't be my call.
I've argued here about the importance of becoming multiplanetary and had many people disagree. Even at just a .28% risk of possibly getting hit with a little rock like this, it's a great argument for building a space faring civilization.
