I don't think anything will need to happen at that point. We wouldn't need to tackle down the top causes of death if the numbers were low, as seems to be the case of bicycle deaths not caused by cars. And when it comes to speeding, it's already against the law, so the technology is only trying to help prevent it. But of course, my enthusiasm is tied to a future where this technology works reliably, so I don't really expect anything like it with all the problems you're describing with current models.
