You know, you might consider some other things. Like nail lenght - Claire could wear her nails very long without having to worry about hangnails. :p
Personally, I don't think Claire has any use for a car - flying is much quicker than big city rush hour traffic any day of the week, anyway. And if she has to be seen using a car, there's always a cab.
Oh, and I can so see Superwoman threaten her reporter colleagues with "no interviews, no quotes, nothing" if they dare to call her Supergirl.
(Maybe half the reporters call her Supergirl at first, but have to reconsider? Or maybe Louis comes up with Supergirl, only to be told not to use it?)
Anyway, I'm really looking forward to reading this story.
