I am seeing more and more speeders pulled over on Colosio so have made it a point to notice the speed limits and try to comply. I am pretty sure the speed limit changes 6 or 7 times between the airport and Bonampak. To me there is not a logical appearing reason for this. There are 3 or so traffic lights but the surroundings, traffic, road quality, etc. are pretty much the same from the airport area to Bonampak. It starts at 80, then 50, then 70, then 80, then 50, then 70, then 60, then 50. As you approach Bonampak, you see the sign for 70 but not far ahead you can see the ones for 60 and 50 within about 100 meters of each other. It is nuts. Of course every vehicle is flying along at 80-90 except when they see someone pulled over, the poor unlucky guy who does not pay attention when, for no reason, it drops from 80 to 50. Do you think the mayor would consider removing all but the 80 kmh signs until approaching Bonampak? It is actually a hazard to be driving 50 when everyone is zigging and zagging to get by you.
