I'm still commuting to work by bike and train, and recently, as I was pedaling up a hill in San Mateo, a delivery van overtook me, and there was a dull thud that almost startled me! Then I saw that it was the paperboy, driving by the single homes at a speed of 20 km/h, throwing the daily newspapers, wrapped in plastic covers, into the driveways every five seconds. Wroom -- Tok! Wrooom -- Tok! Wroom -- Tok! Since Americans don't insist on having the newspaper in the mailbox and aren't bothered if it ends up half under a parked car or near abandoned children's toys, the paperboy manages an average of 12 newspapers per minute. Clever!
