I rented an Avis electric car in Houston in 2022, they told me I had to bring it back 70% full. For three days I searched all over for a charging station that would get me to 70% and failed. When I returned it the woman at the counter laughed and said not to worry, that I never would have been able to find a good charging station since they were all in residential buildings. The public ones were slow and worthless. She didn't charge me for returning with 50 miles left on it.
