I haven’t had to ‘go get gas’ for 4 years. People probably argued “getting water from the well isn’t that hard compared to maintaining all this infrastructure”… but none of us want to go back to that. Completely losing a class of chore is freeing, even if it wasn’t that horrible anyway.
For long distance trips, I mostly agree with you. My habit was always to stop every hour to get a drink and stretch legs so it doesn’t bother me as much. For your 11 hr trip, it would probably add 2 hours.
I'd assume that the parent post compared walking outside your door to a well in your own yard, as used to be the common practice in the countryside, which indeed takes much less time than gassing up a vehicle but obviously not something you'd want to do if you can have indoor plumbing instead.
