I do, if the price is reasonable. Even if the battery is still $100 per kWh, that could be 200 kWh of battery for 20 thousand -> plus the car around it.
So maybe 45k? 45k with incentives available to me right now would be worth it if I liked the car. 600 miles is even more important if it was a TRUCK
People easily pay 60 grand for F150s. .
The reason I want more miles is because where I live, EPA range is fictional. My 2018 Leaf averages 3.3 Kwh on the open road. Meaning since I don't push the lower limit of the battery I get maybe 100 miles. Add in terrain and it can drop a lot further. One of the drives I like to do to go hiking takes me from 2200 feet to 10,000 feet. Even a Leaf plus looks iffy given the lack of charging where I live.
I think having 600 miles or more really just depends on where you live. In some areas it is probably way overkill, in others, its what's needed to replace and kill the ICE. That and charging options... So the question really just depends on where you live, your lifestyle and what your goal is. For a in town or commute only car, it is probably not needed. Heck my 2018 Leaf is overkill for an in town and commute car.
But I can see myself having an EV truck in the future and wanting to tow. Or an EV Class C motor home? What range will that need? Probably a hell of a lot.
