I go by a Tesla charging station every day and see cars there for up to several hours. This seems like a waste of a huge chunk of your personal time so owning an electric vehicle sucks in that respect imo. What are people doing or can do that is productive during this wait time?
Several hours? Those people are parked and charging their car while they are doing something else. It takes about 15 minutes to get 200 miles of range at a Tesla charging station. People sitting in their cars, waiting will be there for far shorter periods of time.
A vast majority of charging also takes place at the drivers destination (such as the drivers home), saving on the time it takes to go to a gas station to refuel (not to mention the time saved from not needing oil changes, smog checks, etc).
As for what to do while waiting, I’ll either use the time to grab snack, go to the bathroom, or watch something on on of the streaming services available from the console.
