- For planes, there were 4,394 near-misses in 2012 [1]
- There were an estimated 5,419,000 automobile accidents in 2010, just in the US, resulting in 32,999 deaths [2]
- And the recent Amtrak train derailment, which could have been prevented (although why the prevention mechanism needs to be in the track, and not on the train itself seems strange). [3] There is also an estimated 2,280 collisions at public/private crossings resulting in 267 deaths in 2014. [4]
The question in my mind is whether the proposed Hyperloop system would be more prone to accident than our current systems of transit. I doubt our current means of transit would fare well under some of the proposed scenarios in the comments.
