What are some unusual laws?

It is illegal to feed pigeons in St. Mark's Square, Venice, according to The Telegraph, which is an unusual law. It is also illegal to run out of fuel on the Autobahn in Germany. Also, in Spain, it is illegal to drive with flip-flops.

Feeding pigeons in St. Mark's Square was outlawed as part of an effort to reduce the number of pigeons in St. Mark's, due to the damage the birds do to historical structures, explains The Telegraph. For safety reasons, it is illegal to stop for any reason, even running out of fuel, on the Autobahn. Spain does not allow drivers to wear flip-flops or sandals, for safety reasons.
