> No analysis of other affects (like sudden stops causing crashes from the cars behind them).
At least part of that effect will show up in these vehicles being rear-ended themselves (as they're exhibiting that exact sudden-stop behavior), and that sort of accident should be reduced if all cars come with AEB.
You'll never be able to wipe out all variables in this sort of study, but I don't think the methodology's as flawed as you're asserting.
It's fair that you can never wipe out all variables. However, a lot of people (especially taeric) were dismissing any attempt to discuss if other aspects were important as "the NHTSA has data and you only have conjecture."
While the costs of phantom breaking are decreased if everyone has AEB, I don't think this makes the roads safer for me unless I want to buy a newer vehicle and I don't want to have to do that.
