> Humans are not safe drivers I see this repeated over and over in this thread, elsewhere on HN, and in many other places on the web. But no one explains what they mean by a safe driver. There are other factors at work than mere human-ness. For instance the US has more than double the number of fatalities per unit vehicle distance than the UK, more than triple per head of population. In both countries the driver is a human yet the disparity in outcome is huge. Perhaps whatever it is that causes this sort of difference should be addressed rather than insisting on a new an inherently unproven technology. Or, at least, give us some numbers so that we can tell what you mean by safe.
