Two points in the article bring up an interesting thought- Will autonomous highway driving make the recharging stops more or less annoying? If you're not actively driving the car, will you have less fatigue and so less need or desire for a 30 minute recharging break every few hundred miles?
On long trips now, is it the driver or the passengers who are more interested in rest stops?
Random thought- the drivers on long distance trips self-select for people who like to keep going.
