I don't remember Nike ever saying or implying any such thing. They, like many of us who were alive when Steve was breaking every American record from 2-10k, prefer to dwell on the good that he did.
Yes, it was fortuitous that nobody else was killed in the crash which was probably caused by someone else crossing the middle line.
Pissing on someones grave is not just bad form, it's meanspirited, spriteful, and incredibly immature. It doesn't take big balls to beat on someone who isn't around to defend themself.
If you've never drank and driven the good on you. If you've drank and driven and not crash then there but for the grace of God go you.
Peace
