As someone who just started commuting back in December (been a mild winter here in NYC) I was wondering how the work attire would work out come summer... I've got a 5 mile commute, which includes a climb up the 59th Street bridge. I might just keep the blazers at work and hope for the best.
As for those nasty cagers, doesn't matter what I wear either, it seems half the drivers out there think all cyclists are menaces.
