It seems like an exaggeration, but driving in Cancun is truly a terrifying experience. What you have to know is that the only rule is that no one follows any rules. So, here's what we've learned. Always dart toward the open space. Don't assume that anyone is going to stay in any particular lanes. The only vehicles more unpredictable than taxis, who stop on a dime in the middle of the street or dart in front of you, are the buses, which will do whatever they want, including blocking several lanes of traffic while cutting you completely off. There are speedbumps on the highways, so don't cruise along with any calmness. The red lights, especially in the hotel zone, are merely ornamental-- the police will wave you through. The red lights in Centro, seem to be similarly optional. But, the yellow lights are fast. So when you see a blinking yellow, slam on the breaks. Mexicans drive extremely fast, as if they are late for an appointment. But, ironically, after waiting at a red light, they start surprisingly slowly. Be patient.
Everything in Centro is nearby. The town only feels large. But, depending on traffic, from Kabah to Bonampak can take 5 minutes or 25 minutes. The only factor that is worse than traffic is the rain. When it rains, it pours! And the streets flood to a good 6 to 12 inches of standing water. This will reek havoc with traffic. But, Mexicans have a good system of turning on their hazards while they drive in inclement weather to improve visibility.
One final note-- when a hurricane approaches, they dismantle nearly everything. So, don't be surprised if the traffic light along with all the streetlights and sometimes even the poles are all removed.
Under the light of the September full moon, the Blatts ventured out to the narrow strip of land in Cancun that separates the lagoon from the ocean to help transfer the female blue crabs across a busy road. Sounds quite romantic, doesn't it? Actually, the traffic was whizzing by and we hand to stomp through the jungle 
undergrowth while being attacked by mosquitoes until we spotted a terrified blue crab. Then we threw a bucket over it and scooped it up. The kids loved it, though, and neither the gloom of night, the torrential downpour, nor the late hour deterred their enthusiasm. Two got away, but we captured a third. I mean we saved a third. The best part was, though, that upon returning to the blue crab HQ, our crab was identified as a female with a belly full of eggs. Our work was done.
