I can grab the data, but the surprising thing about fatal crashes are the typical circumstance. It's an experienced driver driving during the day, in good weather, on a highway, in a sedan style car, sober. There are two ways to interpret this data. The first is we assume that crashes are semi-randomly distributed, so since this is probably the most typical driving condition it therefore naturally follows that that's where we'd expect to see the most fatalities.

However, I take the other interpretation. I don't think crashes are randomly distributed. That that scenario is absolutely perfect is really the problem because of humans. All a crash takes is a second of attention lapse at a really bad time. And in such perfect circumstances we get bored and take road safety for granted as opposed to driving at night or navigating around some tricky curves. And that's a perfect scenario to end up getting yourself killed in. And more importantly here, that's also the absolutely perfect scenario for self driving vehicles who will drive under such conditions far better than humans simply because it's extremely trivial, but they will never suffer for boredome or lack of attention.
