Commuting on the bicycle takes me about 20 minutes (3.5 miles, averaging 10.5 miles with stop signs, lights etc.). Commuting in the car takes about 20 minutes (10 minutes to get out of the garage and past the first half mile). So my TCQ is 1.0

This only fails when I'm on the motorcycle - I can (if I choose to), split lanes (legal in CA) and get through slow patches quicker. Also, the motorcycle is parked outside the door, not in the garage, so I save a lot of time at the beginning. So my fastest commute is on the motorcycle - I'd say about 10-15 minutes.
