Serious question: how do you automatically know that increased demand is from a terrorist attack versus some other legitimate source of surging like the emptying of some venue or unexpected precipitation? The best I can think of is geotagged tweets. This events are also infrequent and different enough that I'm not certain how easy it would be to train a model to detect a terrorist attack. Human monitors would probably have to analyze tweets and determine what's happening and turn surge off after the fact. Even then the right solution would be to leave surge on so that that part of the city lights up on the driver app and attracts more drivers to that part of the city, and then you refund customers the surge price exactly as uber has done during every single terrorist event that I've observed. This is just some journalist published yet another unwarranted outrage piece against the company for the clicks. The unethical company here is the daily mail taking advantage of Uber and a terrorist attack to generate ad impressions.
