Around Grand Mosque, Abu Dhabi. I was driving on single lane bridge that is connected to other bridge, I could not stay there for long. It was in the distance on my left side, (and was full bright yellow color which did not give any glow) while the road was turning right, so I just slew down, wind down a window and stared at the object. The size of it and light was very unusual and then when I slew down, I saw it getting closer and within seconds it was not far behind me but I believe it was without this full light unlike as I saw it in the distance, and the noise that made was quiet. At that point I sped up because I got scared. But after few seconds again I saw similar object on my right side in the distance but bright neon green color. That's all I can say about it. I wonder if military might have their own 'planes' to spy on, I really don't know what it might be. I am not a fantasy person, if somebody out there saw what I saw just let me know.

I saw it as a bright object in the distance and coming towards me really fast. It was right after dark or 1 hour after the sunset. When it was near me, it was without its bright light, only the spot light/ s were on and sound that made scared me. So I did not have the perfect view of it. But when I continued driving, it was again outlined by bright light (neon green) and it was circle with a dome on top of it. The next day driving back home through the same area it was happening the same way, except it was passing by me in a much slower way and almost blended with the dark sky but it had spot lights including one red on the top of dome and drifted in the same direction as the day before. I attached similar photos of what I saw. I see it every day in the distance, even brought my colleague as a witness, hoping it would come close again but that time it did not.
