Many of those features, particularly the early airbags, markedly improve safety only where the seatbealt isn&#x27;t used.  That was and still is a norm in the US, but in places like Europe or Canada where seatbelt use is near universal, the advantage is minimal.  The costs (1000s) are not minimal.  So some would say that removing the airbags and spending that money on other things (ie crash prevention) might be the more efficient approach to safety.
