I prefer to fill up my car with gas, not look for a stupid electrical outlet like a homeless person at the public library.
The nice thing about an electrical outlet is you can put it just about anywhere and most people already have them in their garage. Try doing that with a gas pump.
Even if an electric car works perfectly and is more environmentally friendly than a typical car that runs on gas, they still haven't solved the problem that it's not convenient to own an electric car for the reasons you stated.
