> That effort being what, exactly?

Off the top of my head you could do any of these or a combination.

- much stricter training and testing to get a license

- vehicles where the safety of others is considered

- ban stupid dangerous cars (my wife doesn’t stand as tall as an F350, let alone a kid

- harsher penalties for drunk driving (see Germany)

- harsher penalties for all kinds of dangerous driving

None of these are hard to implement, the US just lacks the will.
