As the Sydney CBD went into lockdown yesterday, the computers at honestly-not-a-taxi-service Uber Technologies Inc observed the massive spike in demand and reacted according to the cold business logic of their programming: they raised prices fourfold. The minimum price for any journey was set at $100, Mashable reported. One prospective customer's quote for a CBD-to-airport trip was a staggering "$145 to $184". Uber Sydney tweeted at 1.35pm, more than three hours into the hostage drama. The company's surge pricing has never been popular. Price gouging, some would call it. But this economic-dry response when people were in mortal fear was particularly tone-deaf.
