Some bosses are suprisngly open to telecomuting once you lay out the advantages to them (and there are some). You can even simply say "If you save me spending 1 hr driving to work each day, I'll do 30 mins of actual work from home for no pay". You might have to work longer, but no commute makes it worth it.
There's also no need for office space for you, you aren't using power at work, you are available more frequently for emergencies (not in the car without internet).
