Zafirah - You are completely wrong. There people that you pay to say they were driving so you don't lose points - I only do things legally so that is not an option for me. I admitted I did it fully and I did not make up some dumb excuse - my inexperience with Doha roads was the problem.
An update as requested:
I went and discussed with an officer in the Traffic department and after they reviewed the video, they kindly reduced the fine considerably. I found them fair, professional and very reasonable. I will still pay a lot, but it was my mistake and I know better so it won't happen again.
