Where is the Transportation Security Administration when you need them?

About 3000 people have been killed by aircraft terrorists in the last 10 years.
In the same period roughly 200,000 people in the US have been killed in car accidents (if that is really the term for it) involving drunken drivers.

So why is so much attention given to the terrorists and so little to drunken drivers?  TSA should have agents patrolling the roads all over the country between 1700 and 0300 looking for drunken drivers.  It would give lots of people jobs, sell lots of cars to the TSA, and reduce the number of people who die on the roadways.
