Uber has run into controversy this winter over their surge-pricing, but in an interview today with The Wall Street Journal, CEO Travis Kalanick was unapologetic, saying surge pricing was crucial to a working transportation market and recent objections to the program were just part of the learning process. We make sure people see it and understand it before they accept, Kalanick told the Journal. If they accepted it and then theyre upset that they accepted it, I think thats just people getting used to dynamic pricing in transportation.
