I know most commuters don't kill themselves on their way to work. You want to get there energized and refreshed, not tired and sore.
I have a fairly short commute (3.2 miles). What's unique about it is the time frame. I work in an on-call position and am allowed to sleep at home while I'm on the clock. When work arrives I have to rapidly dress and hurry to the office. My employer expects us to drive there safely. I bike commute though I have a car, so my standard is that my bike gets to work as fast as my car could. I have lots of Strava logs demonstrating this if the boss ever complains.
Who else has a fast commute?
