Dude, 40% is roughly the share of the market enjoyed by light trucks. EVs share could not possibly be higher then 35%, because that's roughly the percent buying cars cars, as opposed to trucks/SUVs/crossovers/etc.
The question they're trying to figure out is why that 35% or so that belongs to the kinds of vehicles EVs can replace is not going EV. Which means you're basically answering the question "Why aren't Android smartphones dominating iOS?" with a long-ass explanation about how great Windows XP is for spreadsheets. Just as it doesn't take a genius to figure out that smartphones are not going to replace desktops for office work, it does not take a genius to figure out why the 40% of the market buying pickups do not want a Prius. The debate is why people will not switch from a Taurus or Accord to a Volt or Prius.
As for long trips, two points:
1) Everybody thinks they make a lot of long trips. Almost nobody actually does. My family's vacation spots were Piqua OH, and Southhampton, ON. Before I checked I would have thought both broke the 250-mile limit from Detroit. Neither does. Piqua isn't close (180ish according to google), and Southhampton is only 240. But they took forever, and severely taxed everyone's sanity because we were in an Accord and there were four of us.
Thus I sincerely question the sanity of anyone who claims that he spends more then 250 miles in the same car as his four-year-old, on multiple trips a year. Note the "car," explicitly referencing a four-door sedan or smaller. The kind of vehicle that does not have a TV screen on the back console because nobody can see the back console. As I mentioned above nobody has ever wondered why a family that needs a Minivan does not switch over to a Leaf.
2) Hybrids have gas tanks. The 250-mile range you see on something like a Volt means that after 250 miles you stop at a gas station and fill up, not that after 250 miles you stop at a hotel and plug it in overnight.
