I get your point, sure, people like to generalize based on their own perception, it can be useful for some people, or not really useful for other. doesnt mean it's overrated. I think people don't understand fully what Fast charging entails, even thou you never need it, the supporting architecture for fast charging is the important thing that makes a car that do 80kW DC fast charging very different from a 250kW car. Both cars have a very different cooling system, different wiring capacity and a much better overall BMS system, but both cars are fine for most people who dont need it or Never will DC fast charge. The 250kW car will do so much better in Highway cruising when outdoors is 37C, when the pavement is 60C, when you need to fast charge DC when needed. etc. and the battery will also last longer on the 250Kw car since the battery didn't have to stay on the upper edge of the temperature when stressed. The main concept is "overhead for Stress" in engineering. in engineering, you always should leave some overhead, like when you build a house: my pilars that drill down the soil as deep as 14meters, are rated for a 4 story house, but the house is only 2 stores, so that means it was design for 200% overhead, the house only needs 10Tones for that pole, but it can handle 20Tones. 15 years later, I dont see cracks on the wall and the walls all look pristine. same with the Atto3, it's rated for 88kW, I charged at 88Kw, the system is fully saturated at 100%, cooling need to work 100%, the whole cooling system is stressed and that is abuse. The 250kW car: you get 120kW at PTT, using 50% of the car capacity, the car is not stressed at all, the cooling system is not overloaded, and overall the battery will last a lot longer. you dont wast 4 kW on the cooling system, like in the atto3.
