Great link! If there is public transportation options available, why drive to work? It saves money, can save time, depending on traffic and route, is quite safe and you get to play with your smartphone/read/work/relax while doing it.
I usually take the bus to work. It is convenient, especially in Gothenburg, Sweden were we have a bus or tram arriving every 2-5 minutes in heavily used routes.
Btw, want to read some more tips and public transportation related stuff? The Commute Greener! blog is full of them. Something like this may be of interest; http://commutegreenerinfo.com/?paged=3
