Do you say this in a way to excuse the person? If so... Nothing really against you, but my general view on this: I know people who go out and have a big night, then they think that because they slept for 3 hours and now the sun is out they must be safe. I think you'd have to be pretty dumb to be innocenly ignorant of the obvious.
Also, I think that the risk of the effect of alchohol is far more severe and unpredictable than that of speeding. If alchohol is involved in any kind of way.... then grrrrr. Speeding on the other hand, still stupid, but slightly controllable in certain instances.
I did 140 in an 88 Corolla once... down a hill... so no impossible for the Jazz
