There have only been 3 major terror bombings in US history where cars have been used. One was the original WTC bombing. The other two were OK City and Bath School, back in 1927. There were a couple minor car bombs. Most other domestic US bombers of all stripes used pipe bombs or suitcase bombs. http://en.wikipedia.org/wiki/Terrorism_in_the_United_States http://en.wikipedia.org/wiki/Terrorism_in_the_United_States
