Logically, in the rain, cabbies would work longer to meet increased demand and make a tidy profit.
Instead, as told in the likes of Freakonomics, research suggests many drivers set daily targets for their earnings; when it’s rainy they hit that target quicker, clocking off early. On pleasant days, with low demand, they work longer hours instead of raking it in when it’s raining, and then enjoying those summer days.
This irrational myopia costs them their summer – and leaves you out in the cold all because they’re chasing targets, and not reappraising the situation.
