I’m going to be moving into a van in the next few years full-time, travelling around Australia and using gyms for showers and, well, exercise. I don’t know if it’s already an issue over here or not, but I sure hope it won’t be by the time I can move out in the van full-time, cause this is one of the best ways of accessing showers without building one into the van.
I don’t think the article was trying to imply that they weren’t already in use in electric cars, just that they would be better for them.
