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"
[*]DC-to-Delaware Shore,
[*]Philly-to-Jersey Shore,
[*]Boston-to-Cape Cod
[*]Boston-to-Ski
[*]NYC-to-Catskills/Berkshires/Poconos,
[*]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.
