I have been commuting since May when I changed jobs from 25 miles away which would have been an impossible commute (for me) to one 8 miles away - I love it, though at first I did think a bit like you. I do have a couple of very busy roads but don't look for a reason to drive, I actually hate it when I have a genuine reason to drive, the weather doesn't normally stop me, so as a relative new comer I would just say make sure you have a well maintained bike, helmet lights and a florescent jacket and do it
