Well there's your problem. Try doing the same calculation with the average residential electricity cost. Most car use is for commutes after all, so most people can just charge their EV in their driveway every night.
Destination charging and rapid charging are notoriously expensive. It's a luxury product intended for a once-a-year road trip. It is not even remotely representative of your average charging cost. Street-side charging is slightly less excessive, but you're still paying a serious premium.
