I think that Rally just loves her Cobra..., in the manga series she is forever getting her car fixed up, only to wreck it when she's on the job..., Radinov on the other hand, just ran her off the road.., i.e., her beloved car would have been damaged when not 'in the line of duty' so to speak...,
As for road rage in general..., I don't suffer from it (coz I don't drive..,

).., but one of my RL girlie friends is a real Jekyll & Hyde..., she's sweet & demure for the most part, but when she's behind the wheel of her car, she becomes a demon..., forever cutting people up..., screaming & yelling at other drivers.., swearing at traffic lights when they don't change fast enough for her liking..., it's kinda scary being in the car with her....,
