A truck driver in a viral video explained that poor infrastructure and inefficient, heavy electric batteries make it nearly impossible to switch semi-trucks and other large vehicles to fully electric.

Chace Barber, trucker and founder of Edison Motors, appeared in a widely circulated video during an event showcasing his company’s hybrid truck model.

Barber has advocated for a push toward hybrid semi-trucks, as opposed to fully electric, which he said are a bad idea, the Independent Journal Review reported.

“Do you ever see yourself going 100% EV?” an interviewer asked.
