I had a 2023 Prius for 12 weeks on a short term lease. I lease cars on the regular all over the planet as a geologist. It was as fast as the Corolla ICE it replaced. It also was returning 75mpg over ten mile trips on grid lock traffic where an ICE would be lucky to return 15mpg seen both in similar sized cars in L.A. traffic. The highest I saw was 82mpg over a 16 mile trip.
The car shows you a per trip since engine start, per tank, or up too five user defined intervals the MPG,avg speed,avg moving speed, time stopped, distance.
At 80mph it was avg 58mpg over a 440 mile trip including climbing up over the mtns on the way to Vegas.
So I would say your points are conjecture not facts when was the last time you personally drove a modern as in newer than 2020 hybrid? Toyota is kicking butts and taking names with hybrid tech.
I drive a 2022 venza.
Does that count?
It appears your assumed too much.
