Uber also pulled out of Hamburg and Düsseldorf after less than two years of operating in each of those German cities. In Amsterdam, Uber recently stopped offering UberPop, in Paris and Madrid, Uber has been confronted by often violent opposition from existing taxi operators, while in London, local regulators are mulling changes that could significantly hamper Uber's ambitions there. Uber's aggressive tactics have turned off potential customers like Andreas Müller who tried the company's Frankfurt service after first using Uber on a business trip in Chicago. Müller said he liked the convenience of paying through his smartphone, but soon turned against the company after reading that it had continued operating in violation of court orders and did not directly employ its drivers, who are independent contractors. "That might work in the U.S., but that's not how things are done here in Germany," says Müller. "Everyone must respect the rules."
Auger and Amaldi were concerned that the NATO (North Atlantic Treaty Organization) Science Committee was thinking of developing a satellite to put Europe in space. Krige's book states that both scientists '[balked] at the prospect of having European space research located in an [organization] essentially dedicated to military goals, an [organization] which would impose layers of bureaucracy and secrecy on any space science effort.'" This led to the formation of the European Space Research Organization and the European Launcher Development Organization, which became precursors to the ESA. Today, the ESA's mission pipeline is packed with interesting probes set to do fascinating science.
