You may not have reacted in time to prevent a collision, but you very likely certainly would have stomped on the breaks before the impact. Changing a 75mph collision into a 35mph collision is a world of difference in terms of the total energy. I think it's important not to view "collision" as a binary event. With human drivers, it's pretty rare not to heal the squeal of breaks just before an impact. I suspect with automated driving (at least for a while) these kinds of "full speed" impacts will be more common than with human drivers.
