I agree it´s never been 4 to 5 hours. Unless there were no topes on the highway then. But the locals like the topes because they slow the traffic down and make it safer for pedestrians, cyclists, livestock.
The road that serves Pluma Hidalgo was in much worse shape this past winter, with several places where one of the lanes had disappeared down the mountainside. And the road serving Hauatla de Jimenez, from memory of my trip years ago, was also littered with landslides, and the road to Santa Catarina Juquila, etc
