I agree that an independent study would be very useful to get a better idea of what's actually happening. That said, human drivers in the US are bad. We have the highest traffic crash rate among all developed countries by far. Pedestrian and cyclist crash rates have been increasing in the US, one of the only developed countries in the world that this is happening in. Much of the US remains opposed to automated traffi…
> And anecdotally it's common for friends to talk about driving 10-15 mph over the speed limit, and we know speed is the leading predictor for severity of a crash. Most US drivers, especially of higher income classes, are probably well aware that they speed and break plenty of other traffic laws on a regular basis and don't want to reckon with that fact. Because 99 44/100 percent of the time, this is not a factor. Th…
According to a government study into Autobahn fatalities that occurred in 2018, "non-adapted speed" (defined as the appropriate speed for the traffic conditions and allowing full control of the vehicle) was the cause of death in 45% of cases overall. For stretches without a tempo limit it was 46%, for stretches with one it was 50% -- this may be a good statistical for the tempo limits, as presumably there would have been more deaths on those stretches without the limits having been set.
Overall, 70% of Autobahn deaths occur on the segments without a tempo limit for a variety of reasons.
Speed limits on the Autobahn are a frequently-discussed and controversial topic in Germany, but for what it's worth, they're quite actively managed for safety reasons.
