Your point is that we shouldn't have self-driving vehicles because... we can't prove they're not racist? I'm not following. I mean, yes, you're correct that there are edge cases in any moral analysis and it's not just about comparing two numbers (though in safety arguments, yeah, it's almost always about simple numbers). But you don't get to wave that fact as a get-out-of-jail-free card in an argument! You need to show us the edge case. And the best you can do is "the cars might be racist"?
