I'll remember it for two reasons.

A. I think it's important to keep in mind that inflated tires would have just as much oil import relief impact as expanded drilling.  Neither would do much, but nor would either be entirely trivial.  And the fact that something simple and inexpensive and habitual like tire inflation can be non-trivial is very cool.  But the big lesson, I think, is that the people our political system tends to choose to lead our government are not well equipped to deal with huge, long term problems like the fact that the world economy depends heavily on a scarce fuel that both earns big money for dangerous people and the use of which does terrifying damage to the natural systems on which we depend for food and breath and wonder.  They debate largely symbolic issues like tire gauges vs. Alaskan drilling, not big fundamental energy questions, and they do it because we make our decisions based on those symbolic issues, and that's a bummer. 

B. A lot of people in this country do take pride in being ignorant, and that's both dangerous and sad.  Seeing Obama call them out, however, is hopeful.  If our leaders are going to participate in solving those huge, long term problems, they'll have to be more than just populist mouthpieces.  They'll have to be better than the rest of us: calm in crisis, selfless, and open to radical new ideas.  Condemning the anti-intellectual (anti-knowledge, anti-learning, anti-curiosity) attitude is a good step.
