My money is on the bike, but at least the person on the T can read while they wait or ride :)
They've been doing this in NYC for many years, and the cyclist won for at least 10 years in a row. I know that the Scientist and I used to be neck and neck on our commute, but I know I'm a lot slower now that I don't filter. If you can find a route that's all bike lanes, I suspect that the bike might well win though, especially since the parking time is negligible. Who do you think will win? Do you think it's a fair "fight"?UPDATE: I hear a rumor that Josh from Bike Safe Boston has agreed to be the biker- will he ride the Paper Bike?
