Inventions That People Don't Wanna Use Insistently - Turn Signals

TURN SIGNALS
Turn signals are light indicators that lets other drivers and pedestrians to know where are you going to when you are driving 2 wheeler, 4 wheeler or truck etc.

Handmade turnsignal by Oscar J. Simler(1929)

The first electrical turn signals was made about in 1907 by Percy Douglas-Hamilton. Also Florence Lawrence, possibly the first real silent movie star and the inventor of a turn-signaling device and a stop-signaling device. Many cars from the 1920s to early 1960s used retractable semaphores called trafficators rather than flashing lights. LED technology for signal lights was introduced in the 1980s. As of 2013 most countries require turn signals on all new vehicles that are driven on public roadways.

But some people don't wanna use turn signals insistently. I don't know why and i think i will never gonna know. They are so easy to use, even there are penalties for not using them. Man i am not an augur! Tell me where are you going in time! Beside you are shouting at us when a trouble happens. You have small signal and brain, use them!

Sorry Florence Lawrence! People didn't like your invention!
