Rant

What is usually a 40-minute drive became a 90-minute ordeal for me today evening, because of a detour and a number of traffic jams.

This is just a rhetorical question, but I'll ask it anyway: how can two stretches of the same road that carry the same traffic load respond differently to the monsoon rains, with one holding strong and servicing its users satisfactorily, while the other one disintegrates completely?
