Actually, when I bought my last car, I did get the trim level that had all the extra safety features. However, I'm not transporting passengers for money and accepting liability for passengers' lives; airlines do, so their financial calculation should be very different from Joe Blow private car buyer. Finally, if I understand correctly, these extra safety features were software only, meaning they don't cost the manufacturer anything to add on, so there's no excuse to not make them standard. On cars, the extra safety features require expensive sensors, so they really do add to the BOM cost of the car, and putting them on an economy car really could push the price too high for buyers to afford, so carmakers put them in higher-cost models to help make them more commonplace and then move them into lower-cost models as the volumes increase and economies of scale make costs lower.
