SIGNALS

blinkers on cars are invented so that one driver could tell the other driver 

that he's switching lanes or making a turn.

why? 

because humans can't read minds.

there's no such thing as telepathic communication.

you dont expect people to know what you were thinking.

you dont expect people to know what you were about to do.

you have to TELL the other person.

in this case, TELLING the other drivers with BLINKERS.

because that's how you explicitly show your actions.

no mind-reading game whatsoever needed.

but then there's a different case of giving mix signals.

you turn on your left blinkers, but you turn right.

or vice versa.

what exactly are you trying to do??
what exactly are you trying to tell the other person?

i mean.... DRIVER?????

WHAT?????

that you were thinking of turning left but change your mind at the very last minute?

or are you actually plannign on turning left so you turn on the left blinkers, and you turn right instead as a backup plan?

or you actually wanted to make the right turn but accidentally turn on the left blinkers?

or you're so crazy that you turn the left blinkers on for fun 

and without thinking about the other driver, 

you just simply turn right even though you explicitly show that you were about to turn left...

please.

IF YOU KNOW WHAT I MEAN.
