Formula One racetrack ultimately avoided car crash (6)
I believe the answer is:
fiasco
'crash' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Maybe you can see a link between them that I don't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fiasco that I've seen before include "bomb" , "Ridiculous and total failure" , "Total cock-up" , "Ignominious failure" , "Sudden and complete collapse" .)
