I don't think SpaceX has the track record yet to be transporting humans

Well Elon says he has more successful launches that the US based competition, & points to the level of insurance he pays on each launch, and reckons it is much less.

There are compounding factors like the value of the payload, and his charges for each launch which he brags are half the price. But, who, other than Roscosmos have any current track record on transporting humans to the ISS?
