Even before reading the article, my first thought was 'need to expand the range of the vehicle'. Yes, advances in battery technology means even the lowest-common-denominator consumer will get better battery life without having to shell out more -- but that will hit a cap before long. Assuming an average range of about 100mi for the consumer-grade EV, that would satisfy many. But there are still many more who that will not work for, with longer commutes or more driving distance (errands, kids, other activities, multiple jobs, ferrying, taxi/rideshare services, etc.). A dual-engine design seems to be a more obvious solution, with a primarily electric engine with a secondary, small engine providing backup power either with recharge or straight up horsepower delivered to the drivetrain when the battery is depleted or running critically low. This doesn't necessarily have to be ICE; this engine could be something else that's fairly revolutionary like a hydrogen fuel cell. Even if we get to a majority EV situation, having these be commonplace will give everyone who owns one more freedom and options rather than locking them down to what that particular model has (I see a future with more vendor lock-in).
