Yeah, except the sweeteners they use to make diet sodas “diet” make those sodas just as bad, if not worse, than the originals. Which also works for the car analogy given the source of the energy most EVs use :/
We named ours after our blind cat, Musetta. She would walk in straight lines until she met a wall, at which point she would turn and continue in another straight line. She had recently died when we got our first Roomba, so it was like reincarnation to us lol.
