Noticing that Musk dropped the swappable battery model with a very weak reasoning ("people don’t care about pack swap" [0]), and sealed the battery in - like Apple (and others) do with their iPhones - a friend of mine stated that in his opinion the real business was obviously in the batteries. Considering that having a swappable battery may resolve what I consider the main inconvenience of an electric car, namely the charging time, dismissing so lightly the swappable option seems quite odd. What does HN think? Can the total control of the batteries be the real business in electric cars? Thank you[0] https://insideevs.com/elon-musk-comments-failed-tesla-battery-swap/
