A picture is usually worth a thousand words; this picture is worth over a thousand potentially hazardous asteroids.
In an effort to convey how many large asteroids buzz through the inner solar system (and, presumably, to scare the crap out of us) NASA has created a handy dandy overview of the orbits of all known potentially hazardous asteroids, or PHAs. The result? It’s looking pretty crowded out there

I definatly would say something or somebody is watching.. i know we get hit by small ones all the time, but the law of average says we should get hit by large ones much more often than we actually do.
And there are more not shown, not just because they haven't found them, but also because the cutoff size for that classification is apparently 140 meters wide.

That is a lot of potentially hazardous asteroids, and I can see why we always here people say it's not a matter of if it's a matter of when one will hit us.
The Chelyabinsk object wasn't that large, but one thing that occurred to me is that impacts of objects similar to that may be three times as frequent as we record, simply because the Earth is mostly covered by water and I'm not sure we'd get accurate reporting of that type of event over the ocean. We certainly wouldn't get the dash cam recordings like we got from Chelyabinsk, with an ocean impact.

Can you provide some empirical evidence as back-up that shows that we should get hit by more large asteroids than we actually do? Or is that just your "inkling", based on non-epirical information?

It's very difficult for the human mind to comprehend just how far apart these are while the numbers "sound" so high. Sure we get hit but true ELE's are in the Millions of years.
