I find that between 7:30 and 8:00am drivers are the most harried and intolerant of delays. I rode my bike in a little bit late yesterday and no only was there no traffic at all, people were not expressing so much frustration. I wonder if I could simply come to work each morning at a time that managed to skip that window of time if I'd enjoy stress-free commuting every day. You are lucky because there are probably good places to get coffee on campus and do some last minute studying.
