Maybe the specifics of my town are different, it costs ~$60 to go from my house to the airport, thats really good money for 40 minutes / 25kms. Maybe 60 minutes of spent time? (20 minutes to get to me + 40 minutes to get to airport). Expenses on a car are < 50c a km. So $12.50 in auto expenses + $47.50 for 1 hr work.
