A Frankfurt court earlier this month instituted a temporary injunction against Uber from offering car-sharing services across Germany. San Francisco-based Uber, which allows users to summon taxi-like services on their smartphones, offers two main services, Uber, its classic low-cost, limousine pick-up service, and Uberpop, a newer ride-sharing service, which connects private drivers to passengers - an established practice in Germany that nonetheless operates in a legal grey area of rules governing commercial transportation.
