> I wonder if anyone has estimated the impact of "simple" engineering changes on the progress of electric cars. Many years ago, I was browsing through an old Hot Rodding guide to Harley Davidson motorcycles. (Don't ask why.) One line from the book that made a lasting impression was a comment to the effect that real progress was more likely to be found in one hundred 1% improvements than one 100% improvement. As a practitioner and observer of engineering, this really resonates as something with a lot of truth. Even for seemingly transformative changes, they're backed with a long series of incremental refinements until they're actually useful. T
