Why? On my old ~10 mile commute, I could do 8 of it without stoplights, and the MUP was virtually empty when I'd leave work between 9&10 pm. If I didn't go at least a mile between people(generally other cyclists), I was surprised. Absolute safest and most enjoyable commute route. Sure, on weekend afternoons? I'd alternate the MUP and parallel streets that were lightly trafficed/stoplights(or signs) I could safely regard as optional. But that was still much faster than the route google maps would take me.
