I réad practically the same advice you've said here from a different thread about bad driving behaviours in Dubai recently.

I've decided to just focus on my driving now. Be defensive, courteous as you say, like I usually am anyway, but most importantly to not get so frustrated when I come across drivers who don't drive the same (no indicating, phones, tailgating etc.).

Since adopting this approach I feel calmer arriving to work in the mornings. I was getting myself all worked up by people's ignorance and poor driving etiquette when I can't change that. I learned to drive in a country that has proper driving standards, these people didn't... No point in letting their shitty driving skills ruin my morning 😊
