If airbags saved your father's life and you can't have peace of mind with out them, then don't buy a Ford. I can see why you would want to have the side curtain airbags.
However, I, like probably the majority of buyers, (evident by Fords lack of standard side curtain air bags in a lot of their cars) don't car. The only safety feature I like to have is ABS, and even that isn't a deal breaker for me.
