Anyone who ends up sectioned because they are unable to control their own behaviour deserves sympathy. It seems that it's also a reasonable defence in law. However, one would hope that her driving license has been surrendered or removed until it can be demonstrated that she is unlikely to experience another such episode, and if her symptoms are being controlled by drugs, then permanently (the only people I have known who have had mania had a tendency to pronounce themselves healed and come off the drugs, resulting in another episode). Whether removal of a driving license would actually make any difference to someone who is manic is another matter altogether (though I guess it might mean that they aren't in possession of car keys at the crucial point).
