It’s only a four-hour drive from México city to Acapulco. Driving is safe and tolls are not that expensive if considering that it would save you another four hours drive.
This is no news, it is always the same.
6:45 am at one of our high ways -Periferico Norte- going downtown, 9 lanes completely full. Gas is expensive, endless commute (1 passenger per car, average!), one could learn a second language during stops, and we are so used to it.
