BBC 19th century dramas reassure us we may cross the street, hat or no hat. Jaywalking begins about 1915, around the same time as traffic light technology. The police are so concerned for our safety, not to get knocked over by a jalopy. Disconcertingly, police can ask for our identity if we jaywalk. Despite being “staggeringly inaccurate”, with facial recognition technology police will try to identify jaywalkers; easy if your head’s a potato, less so if it’s beatlesque broccoli. Jaystalkers’ facial recognition will contend with a permanent run on hats. Umbrellas, ornate their J-handles, will be fashion all year round.
