U.S. Presidential Limo Defeated by Steep-Grade Parking Ramp

Schneier on Security: U.S. Presidential Limo Defeated by Steep-Grade Parking Ramp:

" It's not something I know anything about -- actually, it's not something many people know about -- but I've posted some links about the security features of the U.S. presidential limousine. So it's amusing to watch the limo immobilized by a steep grade at the U.S. embassy in Dublin. (You'll get a glimpse of how thick the car doors are toward the end of the video.) "
