Ha
Was looking around and found this … a 1920’s version of GPS

Priceless 
So what else is being sold as a great new innovation but has been around for years
there’s a thread on the pointing indicator although its about LED lights the pointed indicator aint new as they’ve been around since the 1920’s at least …
Good find, Nick!
Considering that was in the 20’s, a pretty good concept.
Florence Lawrence (Canadian) also invented a turn indicator for cars in about 1914, but she did not correctly patent her invention.
The device was called an “auto signaling arm” and it was attached to the car’s rear fender. When the driver pressed a button an electrically operated arm raised a sign to indicate the direction of the turn.
In 1918 the Naillik Motor Signal Company (Boston) invented the first ‘totally electric’ signals, using small electric motors to move the arms.
In 1929 Oscar J. Simler (American) patented a turn indicator after stealing the invention from a northern British man.
In 1935 a company in the United States invented a flashing turn indicator.
A Buick was the first production car to be fitted with an electrical turn indicator in 1938.
I know I should really get out more

All that work for people just to ignore them!
Pure genius! Love it!
