The Proper Use of Congress?

First off, I have always wondered as to the efficacy of these kinds of programs:

With a television advertising budget worthy of a Hollywood movie rollout or a tight Senate race, the seat belt safety campaign will take to the airwaves for two weeks, beginning on Monday, with heavy emphasis on the WB Network, Univision, BET and ESPN.

Extensive use of paid advertising, approved by Congress last year, partly replaces events like police roadblocks staged for news coverage of crackdowns on people driving unbelted or drunk. That got the word out to many drivers, but not the ones most likely to drive without belts, men ages 18 to 34, experts say. Those drivers "don't watch Tom Brokaw or CNN," said Philip W. Haseltine, an organizer of this year's campaign.
But they do watch Nascar, baseball, "Fear Factor," "Black Star Cinema" and "Cine de Estrellas," according to the Air Bag and Seat Belt Safety Campaign, which organizes an annual enforcement effort around Memorial Day.

And even if they do, I have to say that this doesn't strike me as appropriate work for the US Congress:

Last year Congress appropriated $25 million for broadcast advertising, of which $9.6 million will be spent by the safety campaign, and the remainder by 43 states. Of the 43, 31 will use the campaign's "Click it or ticket" theme.

It is hardly Article I, Section 8 kind of stuff...

And, indeed:

And there will be a lot of flashing lights: 12,000 law enforcement agencies from all 50 states, the District of Columbia and Puerto Rico have said that they will participate in an enforcement campaign that will run from May 19 through June 1.

"Ads by themselves are proven not to do anything," Mr. Haseltine said.
