You forget a major aspect of full electric that fits well with your discussion: Your house becomes a gas station. Your work becomes a gas station. Just like today's phones which only last a day, you get home , you plug it in. Your main concern would be forgetting to plug it in, just like forgetting to get gas. The car will let you know, and in the case of he Tesla tell you where you can go to charge without any special action required.
