Daily commuter here, ride into work 3-4 days a week.
The good:
-- Plenty of room in the frunk to pack a work bag/lunch/gently folded suit coat/grocery run on the way home from work
-- Big, weird bike = more drivers see me on it than on two wheels
-- I've commuted in every kind of nasty mean weather but heavy ice and driving snow, totally confident on it.
-- GREAT brakes have saved me more than once
The bad:
-- Gearing up (and down) for a relatively short commute is a PITA, but I can't help myself, I'm an OCD ATGATT

-- My Spyder's got to warm up a bit (one bar) before it runs well, can't just hop on and ride
-- MPG nowhere near as good as a two-wheeler
-- No lane splitting (yeah, it's illegal here, too-- but in a pinch in a nightmare of a traffic jam, the option to split is sometimes the safest route... no can do on the Spyder).
Overall? If I still owned a car, I'd probably commute more in the car than on the Spyder. Don't get me wrong, I love riding it every chance I get, it's just not as convenient as a car nor as flexible as a small bike/scooter. Paradoxically, I'd probably enjoy riding the Spyder more if I had a LONGER commute-- it's just a bit involved to ride just a few miles door-to-door.
