I look at it TIME wise and not distance wise.
Currently it's quicker for me to bike to work than it is to drive to work, especially in the wintertime.
I'd continue to bike to work as long as it wasn't longer than ~1.5x the amount of time to drive. After that I'm just wasting time.
If you've ever had a job where you had to drive a long ways twice a day, you know the feeling when you get off of work and say to yourself "I've still got a X hour drive home." (For me it was an hour and a half drive home... very long.)
