You pretty much did that for him. Correlation does not equal causation, and you already mentioned the confounding factors (increased education, improvements in vehicle safety).
That said, I actually think reducing the allowed BAC level probably had
some influence. If you know the ceiling is lower, you're probably more likely to play it safe with the drinks at dinner, even if check stop frequency isn't increased.
