Like many, I remember her only from Top Gear and various other videos. Always smiling and cheerful, even amongst Britain's three stooges, and especially roaring and laughing around the 'ring she loved.
People talk about others "gone too soon" and so forth. Always remember the old adage: everyone dies, not everyone really lives. Sabine lived a full life many, regardless of gender, will not get to live. To the best of my knowledge, which admittedly isn't much, she asked for nothing and was happy to the absolute end with who she was. Be thankful for that; I don't need to guess that she was.
Now she's up there racing among the legends, with Murray Walker, James Hunt, and others providing commentary. Think on that possibility.
Danke schon Frau Schmitz, and rest peacefully. You definitely will not be forgotten.
