Bike time should include time to take a shower.  

Of course, the less heavy traffic and the more commuting time, the more options besides a bike would win.  eg, to travel from my house in Mt. Scott/Arleta to downtown by bike takes me about 40 minutes.  And that's downhill.  By car, it takes me about 15 minutes, 20 to 25 minutes at rush hour.  According to Trimet, it's about 48 minutes by bus (I live only a block from Harold).
