I was hired as a remote employee to a company an hour away. They changed the policy to force us to be in the office 3 days a week. My solution was to just count the commute as part of the work day. It is an arbitrary job requirement so it's fair.
I wonder how many people have tried to say that their drive into work is part of the work day. I would be on the phone some mornings on the way to a clients office and would occasionally bill for that time depending on how productive it was. I'm sure an attorney bills for every block of time no matter that is done during it.
