This was well before 9/11 - about 15 years ago. And there was nothing
to stop someone going around the long way if they wanted to do
deliberate damage. It was trucks running off the freeway they were
worried about.

And when you consider that someone going into a data center could shut down
Visa or a telephone company, you are dealing with a catastrophic situation
should someone crash into the building.

Definitely - but companies also insure against these type of
disasters. A lot of these sort of precautions, and even normal DR
arrangements, are driven by the insurance companies. I know there are
businesses out there that only set up disaster recovery plans because
their business insurance requires it. If it was up to them they just
wouldn't get around to it - however much of a good idea it may be.
