Well people are naming their children after cars here - look at Kia! Besides, Renault used the Zoe name back in about 2004 for the little Zoe concept which was supposedly meant to preview the Twingo. There are tons of products around that have human names - look at the Henry, Hetty and Charles vacuum cleaners! Mercedes! Mind you, Renault might not even end up calling it Zoe.
I've got an Aygo and a Meerkovonian meerkat :)
