I have four options-

1) Drive. It takes about 30 minutes. I'm lucky in that I have a freeway near my house that almost goes directly to work. It would also cost $20 a day by the time I paid for fuel, tolls and parking. If I stayed off the freeway, there would be almost nothing between riding and driving.

2) Ride. That takes about 50 minutes, and costs almost nothing.

3) Walk to the station, then train. Also around 50 minutes, but costs $10 a day in fares.

4) Drive to the station, then train. Around 40 minutes, and about $6 a day in fares (I drive to a further station thats in a cheaper fare zone).

Riding also means I don't have to worry about exercise, so it's well and truly worth it for me, even if it's a little longer than driving.
