Drive carelessly flattening farm animal? (9)
I believe the answer is:
oversteer
But I can't explain it at all! Could you help me understand?
(Other definitions for oversteer that I've seen before include "misjudge a corner" , "Mechanical fault in vehicle" , "(Of vehicle) exaggerate turning motion" , "Fault in vehicle's performance" , "(Of car) turn more sharply than intended" .)
