The False Positive of Self-Driving Cars

I just worry about this kind of false positive thing, like more complexity into a scenario than is necessary. I suspect it's extraordinarily rare and that number is only going to go down. And by planting the seed in the code, you're just going to make the cars drive into the back of lorries all the time when they didn't need to. Everybody can talk about the funnest of the various moral situations, but it's much harder to talk about how to self-driving cars really work.
