People just need to get less rushed, learn what a proper following distance is and actually drive the car.
That's hard to argue with... but does a proper distance include enough room to account for an unnecessary panic stop on the freeway?
If your car on the interstate is doing 75 or 80, and it decides to slam on the brakes because of something like a tumbleweed or a plastic bag, the chances are there is going to be a collision. Ordinarily, people don't make irrational panic stops at high speed, but an automated system will.
Hopefully it won't be a semi-truck with a full load behind you, but it could be, and that is part of the unintended consequences of a "safety" feature.
Air bags are another example..
Although originally intended to assist in prevention of injury from someone who isn't wearing a seatbelt, they have also caused deaths in situations where an occupant would have survived without them.
In both cases, likely the positive outweighs the negatives in the majority of cases, but in any specific circumstance, your results might vary.
Based on forum feedback, I leave a lot of extra distance when following a late model Subaru and pass at the first opportunity.
It's windy very often here and you never know when a "killer plastic bag" may be coming your way...
