As long as your minding your own business and not weaving in and out between cars on the road, the police will leave you alone.. If your in the fast lane, it dosen't really matter how fast your going lol.. you just flash your high beams to whoever is infront of you and ppl get out of the way.. Its a good system! Although I tried it in the U.S and I get break checked everytime :nono:.
If you ask for it though, Dubai Police will getcha!
