Considering that each time you are driving your it costs money to you and the society and reduce your health and life expectancy unless you exercise separately, that cycling and walking improve your life expectancy while saving money to both you and the society, and that a 12 minutes drive can't be much more than a 40 minutes bicycle ride, my bet is that riding to work would be a better option for both you and the society as it would save everyone money[1] and time while improving everyone general health and life expectancy. [1] combining exercising + commuting will make you gain time over commuting faster + exercising separately in that kind of distances.
