alt Hacker NewsThe curve is mostly flat for EVs because they started with such high efficiency to begin with. At their best, internal combustion engines are quite terrible so there has been more room to make improvements.
Even so, the vast, vast majority of cars in the past 100 years have had all of the technical innovation of a washing machine (and that might well be underselling the washing machine!).

10% a year on average, something like that? ICEVs haven't had that kind of incremental improvement in a loooooong time.
You have to zoom out a bit. EVs are still improving of course because they are relatively new. It's not fair to compare that to the last few decades of car history. You can make any flat looking graph look steep by zooming.
