I own a Tesla. Love it-- due to the ease of charging and lack of issues when I can use Tesla chargers. I rented a Hyundai EV last year and it was a hassle. Like the article pointed out, you have to have an App. There are 3 different ones I know of. There were so many charging issues, I returned the car with about 10 miles of charge left on it because I could not charge it anywhere! It's like if you had an appliance with a plug. But that plug won't fit in most sockets. Then if it did fit, you have to have a special app that works with that plug. Then you have to understand which socket you are using. Is it socket A, B, C in wall X, Y Z? You just can't use the power in that wall without first giving up all your personal information. Oh yes, good luck finding the socket to begin with. Charging stations are usually hidden in the bowels of buildings, parking lots and if you do find them, good luck if they are in working order.
There is so much opportunity in making EV charging easier, faster and better. Like standardization and networks. In the US it is loosy goosy. I would love to only rent EV's when I need a rental car. but charging is a hot mess. Unless I was renting a Tesla and can charge at the various types of charging stations Tesla offers.
Also, building more charging stations. I need to go to Idaho and Montana this summer, but we have to drive the fossil. There aren't any charging stations where I need to go. Another issue.
