BMW of North America's VPC in New Jersey actually made an error in all the cars they processed in the March of this year- the window stickers listed the option as "Rear Side Impact Airbags with HPS", when infact it doesn't have Head Protection System! My first 323i had this error on the sticker, and I got two new window stickers as well as a letter of apolgy from BMW of North America.
NO, Rear Airbags doesn't include HPS. Now even the VPC knows that :)
