Indeed, especially in night conditions. It took 10-15 minutes to figure out why everyone honk at me despite the signal is still red. At first, thought all drivers in this country are color blind(in particular green/red). Finally I discovered that, in Mexico it is against the local-rule halting the car while the signal is red. All you have to do is sneaking in the intersection(doing it "carefully" would be preferable for your safety) and try to go forward as possible as you can. If you see someone(vehicle on your left/right) coming at you that would mean you may stop there. That way, I'm sure no one gives you a honk.

I have also discovered that every trucks/busses are spewing black smoke incessantly and its quantity looks horribly tremendous. About 1/6 of the emissions on this planet must've been produced by them. Obviously, mechanics in this country are color-blind(in particular black) or probably no longer exists. So... Make sure windows shut and A/C set at "recirculation" position while driving, otherwise your face getting black.

Also, You'd better watch out for 1) speed bumps: the size(height/length) far surpasses US standard, you and your car could get damaged. 2) livestocks: they show up unexpectedly.(I have seen them on 92D LIBRE, not CUOTA). IIRC, insurance doesn't cover animal collision.

I was supposed to be in Acapulco this summer. Although, the vacation plan has been overruled by my boss, am going to go to there again.(maybe next summer, flying to MEX and then driving to Acapulco) Hope all toll gates accepts C/C until then. I hate bringing cash with me.
