Fast personal transportation is so high utility that people will dismiss many externalities. If you offered teleportation anywhere in the world except it would pick a random African and kill him at a 1E-6 to 1E-4 chance (depending on your skill at Tetris while being teleported), I suspect many in the West would do it without a question.
We already do similar stuff for oil, uranium, and cobalt.
And what indication do you have the opposite wouldn’t happen if the tech were available for them to use with the same caveats except the victim having to be from from somewhere outside of Africa?
If you spent an hour watching traffic in Lagos, Nigeria, you'd see that West Africans themselves value the utility of personal transportation above the safety of their neighbors on the road.
