The Problem
You are driving your Tesla Roadster to the beach, and you realize you have less than 25 miles worth of battery life left. You need to find a charging station right away.
But as you drive into town, every charging station is occupied by someone’s electric car. And then, when one does become available, the station’s payment system malfunctions. You do not have enough energy for another road trip to find a new charging station with working payment systems before your next meeting. So what do you do now?
