That means 600km becomes 400km or less at 80% charges, and when you drove 140km/hr or more, the acceptable speed in many US states, that means less than 3hrs, and 600km isn't rated at 140km/hr speeds!
In other words, EVs don't work for long range driving.
Some may drive slow, or not count the 10 minutes to get on/off road and find a charger, and the 20 minutes to hook up and charge, and the potential to not find a free charger.. but I did.
And when I used these sensible, real world values, a trip from Quebec to California, which I take from time to time, changed from 3 days, to 8.
Lots of people drive like this. Lots. Especially Canucks wanting to escape snow, darkness, and wolves.
I've seen all the replies before, and all of them take some random thing, which I base on reality, averages, and fact, and try to pretend that ot doesn't matter.
But it does.
As others have said, if you are city driving only? Great! And many families have two cars, and that's another great place for an EV. One EV, on gas.
And we will get there range wise. We're just not even close yet, for long drives.
