You're right, I left some pieces out for brevity. To elaborate, they were not picking up the Tesla from Austin and started for San Antonio straight away. They were vacationing, and as all vacationers do, they went sightseeing, eating out etc. and by the time set off for San Antonio, were not sure if they'll make it, then charging was an issue. Multiple factors combined to convince them that the Tesla is no good when you don't have a plan.
