Does the Leaf specifically have this, or are you merely speaking of EVs in general? Clearly, your statement that "many people do this" does not apply to the Leaf, since the Leaf is not yet available. Of all the EVs I am aware of, only the Tesla Roadster has a partial-charge option. While I could unplug my Xebra before it is fully charged, I'd have no way of knowing how much of a charge it has. It could well have more or less than I wanted.
The partial-charge option on the Tesla is a great feature, but is more related to the characteristics of the particular type of lithium ion battery pack, which has a longer life when charged only to 90% than when charged to 100%.
Do you know for a fact that the Leaf will have this option?
And even if it did, it would not completely address the issue of downhill braking because an owner might not utilize it, preferring instead to maximize range.
