Sat Nav

"TURN LEFT."
He knew he shouldn't turn left. Not yet, anyway.
"TURN LEFT."
Fuck it, he thought and turned left. Straight into an alleyway.
"RETURN TO HIGHLIGHTED ROUTE."
Bloody stupid machine. He stopped and reversed out of the alleyway, back on to the main road. He continued driving in the direction he had been driving.
"TURN LEFT."
He sighed and continued to drive.
"TURN LEFT."
He ignored it.
A large spike appeared from the sat nav and thrust into the man's throat. He screamed.
"TURN LEFT, MOTHERFUCKER."
He turned left.
