I'm sorry, what? Since when is a product that meets all realistic use cases of a smaller portion of the population expected to sell better?
I have a sedan. It gets me 20 miles to work and 20 miles back every day, and 50 miles to the remote site once every few weeks. It also gets me 300 miles to the parent's house and 500 miles to the in-laws once or twice a year. On the rare occasion I need to go farther, I fly. On the rare occassion I need to haul a big load, I use the wife's station wagon or rent a truck. I sure as shit don't want to be borrowing a vehicle too often or renting a truck more than maybe once a year or less. So an electric car that causes me to have to do that wouldn't be on my radar. I'm pretty sure a good fraction of your 40% would agree, let alone my 60%.
