It's really not a sunken cost fallacy. It's good evidence that the "think of the terrorists" angle is overblown. There are plenty of other problems with self-driving cars, but not that one.
And plenty of other problems with missiles before that one too.
As the news dramatically reminded us recently, the number one cause of non accidental casualties in plane is being shot down by the military, by a very large margin before terrorism. Similarly it is not hard to guess that car related casualties due to terrorism is never going to be significant compared to others.
Terrorism overall is not a big issue, despite we like to think that our main problems are caused by a few malignant individuals.
