Swishy, the driver of that Chev would be getting boulder and boulder.
In the good old days (about 15 to 40 years ago) that flashing green light in the BMW meant that the car was going to turn left no matter what the driver wanted. These days, they only come on when you play with that little leaver on the steering column.
When I got my driver's licence on my sixteenth birthday my car, a 1948 Vauxhall, had trafficators (those little arms that came out and lit up to indicate a turn) but my driver's questions required me to describe hand signals for left and right turns and a stop. Years later I got my heavy combination licence and there were no questions about turning indicators.
The day before yesterday, I entered a roundabout in town and a middle aged lady approached from my left indicating a right turn. Even though I had right-of-way, she entered the roundabout and turned left. She continued for a block and then turned right into the carpark of a pokie venue.
I have my shoulder to the wheel,
my nose to the grindstone,
I've put my best foot forward,
I've put my back into it,
I'm gritting my teeth,
Now I find I can't do any work in this position!
