I drove a leaf for 3 years and it had 80 to start with and ended around 67. At the end, it was a pain, but didn’t notice until around 70mi range. Somehow, 75 would get me from home, to the airport, to work, and back home again with room to breathe. At 67, it was nail biting.
To the point, 150 is probably good for quite a lot of people.
