motorcycle mailbox and old motorcycle laws

The motorcycle, built in 1884 by an Englishman named Edward Butler, looked pretty silly. It had three wheels, not two, and was really just a tricycle with a motor. Nevertheless, people were afraid of Butler's motorcycle, so afraid that they asked the government to pass laws against the new machine. One law said that there must always be three people on a motorcycle. Another said that a man with red flag must run ahead of the motorcycle, waving the flag and yelling to warn people that a motorcycle was coming. The old motorcycle mailboxes can look ridicule, but not so ridicule like such laws.
