60kWh should be a tipping point in EV use. See this great article, Can EVs handle the distances we drive
? (from which I've linked the illustrations, below)
Key to understanding this is to see that EVs need not duplicate all trips for all people. They just need to do near-all trips for, say, 80% of people, to be in the choice set for a revolutionary, world-shattering 30% to 50% of car buyer (recall that it would be a radical growth in EVs to get to 10% to 20% of cars sold. Lots and lots of single-car and two-car households have people who don't like to drive more than 3 hours, ever, and who switch to other modes (air, rail, bus) for longer trips, regardless of the range of their ICE car. They don't *want* to go farther than a 60kWh car can take them.
95% of commuters travel less than 40miles to work. Those that do go that far are probably driving at 75mph+ speeds where drag matters A LOT. Even so, let's say that to the Leaf 40miles of 75mph+ driving burns 80 miles of range. A 60kWh battery should still have the mostly covered. (not that that market it worth chasing in a Leaf: it is either, today, people who don't care (and do it in an F150) or do care (and do it in a Prius). Ergo, 60kWh = far more than an EV will ever need to be a "daily commuting" car for 95% of commuters (e.g. the mass market for EVs)
But wait, single-car households will take "weekend getaway" trips, say 5x a year. These could be key. How far are those trips?
To quote myself, such trips are, almost by definition--trips of roughly 2hours and roughly 125 miles. Any closer than 1 hour, and it wouldn't be a getaway (you'd just have reached the exurbs of your metro area). Any farther than 3 hours and it is no fun to do in a weekend for MOST people who can then consider EVs (and those who "love to drive", yeah, they'll keep considering only ICE/hybrids)
Two hours and 125 miles feels "away" but not "too far"
[*]NYC to The Hamptons or Atlantic City
[*]LA to Palm Springs
[*]Seattle to San Juan Island(s)
[*]Sacramento - Lake Tahoe
You can see this in that people do drive >160miles about 1% of the time or less...aka back and forth 2 weekends a year
Some "stretch" distances
[*] Vermont Ski (Boston to Killington = 160 miles)
[*] Hartford CT/ New Haven to Hyannis Cape Cod 160 to 180
[*] Chicago to Wisconsin Dells = 180 miles)
[*] San Francisco to Lake Tahoe = 205 miles
[*] Here's a whole list from LA, mostly in the 50mins to 2hours range
And then all kinds of once-a-year trips that are in the 4hour to 5hour "big vacation trip" range;
[*] St Louis to Ozarks
[*] Atlanta to Hilton Head
[*] NYC to Lake Placid or Vermont
[*] LA to Vegas
For which renting a car or going by bus, train, or plane works quite well...and for which I know plenty of people who own ICE vehicles who nonetheless rent a car (cheap) for this kind of special trip because their usual ICE is either a "workhorse" or older and no fun on long trips.
