Sure. And we are much more likely to die of old age. I am not being rhetorical here...but...do you see a difference between being killed in an automobile accident and being killed by someone with a car bomb?
The last time anyone in the United States was killed by a car bomb was in the World Trade Center parking garage in 1993. Their may have been incidents involving Tony Soprano types in the interval, that I am unaware of, but unless you are in Tony's line of work, thats a non-issue.
The odds of your being harmed in any way by a terrorist are so infitesimal, as to be practically non-existant. If terrorists want to blow things up, it will happen, and there is absolutely nonthing even the more draconian government policies can do to stop it.
