I used to leave my car overnight and split my commute between days. But that required keeping the bike rack on the car ALL THE TIME which sucks on the gas mileage and stuff. For nearly a year now I've been doing my full commute each day, twice a week. Car stays at home. I do stuff sometimes on the weekends that requires use of my car so I can't really leave it at work.

My car is 20 years old but it's still one of the top stolen cars in the nation so I don't like leaving it unattended for long periods of time. I *never* take my car to the mall or movie theaters, we always take my wife's car.

We have a few company-owned vehicles so I can easily go to meetings or job sites, etc. on days I ride the bike to work.
