Long, but spot on. Handling is how well a car does what you ask of it.

I have to add that handling needs two definitions. Around town and performance. Around town, never losing traction, never doing any emergency maneuvers is a typical test drive. Emergency avoidance, unexpected road conditions, etc. fall into the performance/traction loss category. Some of us rely on professional testers before buying, others just ignore performance handling.

Hence cars that many find acceptable or good handling fail the moose test and/or become dangerous in emergency situations.
