Or you do your taxes, respond to emails, call friends/family, plan your next family trip, all that stuff that can be done remotely and that you otherwise would've done on sunny sundays and whatever and come back fully available ? Doesn't sound that simple to me.
It doesn't matter! I could be doing anything, ANYTHING, and it'd still count as working hours. If the company doesn't want you to waste time traveling, you shouldn't be traveling.
