A massive communication campaign should be done to target the bicycle users, I believe that they are construction workers and port workers mainly, NOT to go on the road with a bicycle in the wrong lane and in opposite direction of the car.
How many times do I cross in a week, a bicycle coming straight in front of me. One day, I’ll probably kill one, cause sometimes, the space to avoid this guy is very limited and most of the time, they appear in the last moment (in a curve, hidden in an interchange, etc…).
There’s not really a need to fine these people, but just to educate them and explain them that they must go in the same direction than cars, and only drive small roads, where cars are below 90 kph.
not just construction workers, I’ve had similarly scary situations in Jumeirah with cyclists on expensive road bikes in replica racing clothing.
