Your second question first: you will bring your AFORMS printouts with you to your interview and yes, the interviewers are very good at reading them. This is five-year old info but at my interview, they spent the first 15 minutes (about) pouring over my AFORMS printouts without saying a word. Then they handed them back and began their first question with "so in 5 minutes, tell us about yourself."

The taxi time question would be better addressed by a more recent new hire, but my opinion is to go ahead and add it to your on-line application if they mention you can. If they address it on the web site then they certainly expect to see a difference between your total time on your app and whatever source documents your bring to your interview.
