@missileman: In all fairness, I didn’t say I was against seatbelts. IMO, that is safety done right: cheap, simple, effective. Third brake lights, too. (About as attractive as a boar’s bottom, but whatever.)
Since belts have been widely available since Sinatra was an up-and-comer, I’d call that “proven technology.” I also think it’s largely irrelevant if they are or aren’t mandated today: I can’t see any manyfacturer selling, or customers buying, a beltless car.
I was more concerned with over-reliance on unproven tech for diminishing benefit. In addition to the Honda recall, I was thinking of Ford’s issue with certain “eco-bust” engines catching fire. As you recall, the root problem involved an electronically-controlled water pump that wasn’t cycling on properly. A “tried-and-true” belt-driven pump could’ve avoided the issue entirely, at the cost of, perhaps, 0.1 MPG or so…
(And let’s not forget Toyota’s DBW fiasco. How could you, really.)
