Are there any companies out there that try to predict these price hikes and recommend the best time for you to do something? As in, "I noticed that you're asking for a cab. If I were you, I wouldn't be in a hurry, ask again in about half an hour and you'll get a much better deal." "I see you're at a bar. You should probably hop into a cab sometime soon, the prices are about to soar." Bonus points if you can use multiple sources at once. "I know that you heard hotels in Houston are going to be expensive next week so you rescheduled your trip for next month, but if you go to these restaurants and use this deal for car rentals, you'll end up saving money overall by going next week." Obviously we're a few years away from those kind of recommendations, but is anybody working on the core idea of predicting when it's best to use a given service?
