If suddenly braking causes an accident it's because someone was not following at an appropriate distance. You should always allow space for unforseen hazards. It's actually the law. If both cars have AEB even that unsafe condition becomes a non-issue. Just because humans have adjusted to regularly driving in an unsafe and illegal manner does not make it the safest way to use roads.
