What are the risks, by the numbers? How many asteroids hit Earth and how many can we expect to zip past us?

So just a 1 in 20 chance for an undetected asteroid with 1km diameter that could cause global civilization collapse.

This is fine. /s

On a serious note, it will probably take an actual asteroid hitting a city for governments to invest more into asteroid detection and defense

Unfortunately true. The only way to get humans to collectively want to deal with space is a threat from space. Once life's are threatened all of a sudden it's a fast track to build defenses and bases to protect humanity. Honestly if it means allowing some humans to die to allow humanity to live longer than so be it 🤷. After all the end goal is to not go extinct.
