My family's old Dodge Caravan did it, and the van before that, as well as 2 sedans we used to have (forget which). My sister's Celica almost has it (no back doors). Both of our current Camry's do the same thing.
The thing is, kids are supposed to sit in back, and a lot of kids think "hey, I wonder what it'd be like driving at 45mph with the doors open!" (I did, at least), and so locked rear doors don't open from the inside, while front doors do.
