Mark B is wrong.
It is/was available on a wide variety of vehicle brands (past and present)

Volkswagen
Audi

jaguar assist (the rumor is that it will be available for all ford brands in 2010)
Holden assist (AUS)

Bmw and Gm both offer retrofit systems (im not positive about jaguar or rollsroyce). If i recall correctly, they are only for those brands.
