What makes you happy when commuting?
As a compliment to the 'what may annoy you when commuting' thread, how about what makes you happy?
I'll put the standard answers up front. Fresh air...exercise in what would have been wasted car time...
For me it just feels more free somehow. Even though I can go further and faster in the car, there is something about being in the open air with nothing holding me back but my own legs.
