Request #597 From Lori

I’m looking for a YA novel written in the 1980s about a society (probably futuristic but not obviously so) where everyone “lived” in their own personal little automobiles. The people had legs but never used them because they just lived in these little cars. It’s sort of like they were half human with the bottom half cars…except that at the end, I remember the teenage girl who was the protagonist drove down the highway and got out of the car and stood on her legs for the first time.
