I was wondering if the age had something to do with it.... pretty sure my old Ford Escort in the UK did not have seatbelts in the back. Your logic is flawed, the absence of seat belts does not define it is not intended for passengers, any more than the absence of a TV ! The presence of a seat cushion, a backrest cushion, seat pockets and windows, cup holders and an ash-tray, say the space was built for passengers!
