This is kind of a weird take. I don't have petrol at home to fill my car's tank either. Obviously if ammonia engines took off, it would be available for refueling. That said, I have no problems with alternative fuels being researched. I am not even sure if EVs will ever be practical enough for widespread adoption. Many people don't live in single family homes with easy access to recharging.
