POLICE IN CANCUN ARE CORRUPT !!! DO NOT EVER NEVER RENT A CAR THERE
we just got back, rented a car got pulled DRIVING to our hotel. senor told us "pay 60$ or we'll take you to police station and take your licence" Gave him $60 dollars, he put it in his pocket, no paperwork involved. then we noticed a police car with the lights on every half a mile or so. They will wait for you on the returns from one direction to another, this is where you slow down/stop and they can clearly see the rent sticker in the top left corner and judge by your looks are you worth the shakedown. Other times they will start trailing you, and if they notice you have the sticker in the window, they 'll stop you for a shakedown. We drove total of 4 times and got pullled to pay cash for nondescript reasons 2x with threat of keeping the licence passport and taking you to the station. In hotel they told us that these guys pocket the money and that we should call the hotel and concierge would talk to them (? hotel person arguing with the p[olice in your behalf?) , but after 50% shakedowns and two other families naive enough to rent a car got $250 for "running the curb" and $100 for "no seatbelt" we parked the car and did not use it. Do NOT Drive with your passport/licence or any money, they will just take it. When we complained at AVIS they just laughed at us, clearly knew about this, I am not sure whether they are more involved, the indentifying "rent Sticker" that helps police shake you down is placed by AVIS/other rent companies
DO NOT EVER NEVER RENT A CAR IN CANCUN /YUCATAN PENINSULA !!!!
