it is deeply ironic that a toyota hilux pickup truck - an actually practical pickup truck - does not meet US "standards" but the pedestrian killing, inefficient, wasteful, and expensive "pickups" from US auto companies somehow do.
Edit: My poor phrasing certainly did read that way though, I should have been more clear.
Nobody has said the Hilux can't be sold in USA. Toyota simply hasn't tried.
And to echo others...blame the chicken tax.
