Course, that was back in the 1990s.

Could they use faster stuff? Sure. Would there be any business value? Probably not to justify the development costs. I mean, obviously an ASE tech isn't waiting for four hours, they are off multitasking.

And we all know that car manufacturers value their production costs WAAAY more than they value the mechanics time. Horror stories like pulling the whole engine just to replace an alternator.
But the development costs should not be passed to the consumer. My 2 cents..
