She is a silly, thoughtless, immature, self obsessed girl, who thinks, like many do, that what she says on twitter is amusing to her freinds, and thought like many do that what she wrote was between her and her friends. Also, like many young people she was not prepared to take personal responsibility for her actions, both for the accident, and for silly childish uninformed remarks on twitter. For that she will have to have that hanging over her for the rest of her life, because it will be forever on the Internet, for all her family to see, her children and her grandchildren. As for the driving offences for which she is charged, she is entitled to her day in court, I doubt very much she will get away with it, but the punishment will no doubt be proportionate to the offence, though many cyclists on forums across the country will disagree with it.
