Not surprisingly, demand for ridesharing services like Uber and Lyft tends to drop in January. You don't have all those holiday parties to visit, and you're usually back to the daily grind at class or work. Uber knows this all too well, and this year it's determined to do something about it -- the company is slashing fares in over 100 North American cities this month, 80 of which will see the cut on January 9th. How much the price drops depends on where you live. It'll be a relatively modest 10 percent in Los Angeles and San Francisco, but rates are dropping by a tangible 20 percent in places like Houston.
