Sorry but what about the folks like me that would have to walk 8 miles to get to the closest bus stop to get to their job? Before anyone says get a job closer to where you live or move closer to your job, that just isn't feasible.
Walk 8 miles? Try biking there instead, it saves a ton of effort (your arms eat up most of it when you run). It helps you stay in shape and gets you a breath of fresh air. Once you arrive, use a lock to secure your bike (there ought to be bike racks along the way).
I don't know about anyone else, but the buses I see allow you to bring the bike onboard as well. This means that you can park it at the office, where security cameras ought to be. If not, then bring it inside. If you get a decent lightweight roadbike, it shouldn't be hard to manhandle.
