Last year my job moved. Previously I lived <5 mi from work. Rode to work almost every day. Car free? No. Just enjoy riding. But it did keep my car mileage down.

Now I live ~25 mi from work. Tried combining the light rail with riding. The light rail takes more than an hour to get to the ride part. Then I had a 45-60 min ride to work. Reverse at the end of the day. Driving to a park and ride takes less than 30 min. Costs more but that extra hour a day is worth it to me.

Currently I drive ~20 mi, ride ~7 mi each way. 14-15 mi/day is about right for me. About ~75 min each way. Not even considering getting rid of the car.
