Things like the double-nickel NMSL that was, thankfully, discarded in the mid nineties, the .08 BAC limit, or the legal drinking age of 21 years, all which were adopted nationwide as the result of coercion from the Feds, are the perfect car analogy for this situation.
A majority of the states have highway speed limits of 70+. No federal highway dollars are currently tied to speed limits, just as no federal education dollars should be tied to dysfunctional standardized testing. In fact, the current model of taking away money due to poor testing performance practically guarantees that bad schools will remain bad. I'm not saying that money is the solution to every problem in our schools, but the proper application of sufficient funds can make a difference.
