You have the arm flapping from the driver’s side, up and down. There are a variety of hand signals that you will encounter, and not the one’s involving a middle finger. Bend the elbow at a 90-degree angle so that the hand is pointing up and your palm is facing forward.
If you can’t be reliant on a car’s indicators and lights, then what kind of car are you driving and why on earth is it on the road! Extending your left arm out of the drivers side window. What on earth do driving instructors teach new students about the sticks attached to the steering wheel! You have brake and indicator lights at the rear of your car, and that’s what I am looking at people! Not your flailing arm doing an audition for Swan Lake. To add extra annoyance to me whilst I am stuck behind a car that has an arm flapping driver is that they do not use their indicators either! By then, I am screaming and biting the steering wheel. The slow down ones, the “I’m turning right”. The same ones you would use whilst performing your cycle proficiency test.
The lack of using an indicator or the hand signals. I learnt to drive in London so city driving, honking my horn and using language that a builder would blush at is common place to me. I must add that I lived in Dubai for 5 years and thought that I had seen every crazy driving move known to man and felt grateful every night when I got home from work, car and myself unscathed. Many things annoy me about the standards of driving here.
