What's your commute like? There are many aspects to the RTO vs. WFH debate, but having to waste away 1-3 hours a day on the road, coupled with the energy use in the OP, really cancels out the mental health aspects of being in office. It even detracts from the amount of work done.
The London office commute is 30 minutes train and 25 minutes walk. I really like that balance as it gives me sunlight, exercise and fresh air.
I work from a library on the other day, thats a 30 minute drive. I tend to leave before 0700 when the roads are peaceful. My car is pretty fuel efficient, i try to hypermile it and get ~50mpg.
