South Korean capital Seoul could potentially ban Uber in the city, in favor of its own still-in-development app. The city government advised that it would try to ban the car-hailing app, as current South Korean law makes it illegal to provide any sort of fee-based transportation service via privately-owned vehicles not registered to do so with local authorities. The Wall Street Journal reports the city is working on its own similar app for registered cabs, allowing users to see the locations of nearby rides and driver ratings, and is aiming for launch in December. The city’s government has previously requested for police to investigate Uber, and though this stopped over a “lack of evidence,” the city is asking for the inquiry to continue. One Uber driver has already been caught by the city in April, and received a fine of 1 million won ($975) for driving a rented car for unregistered taxi-related purposes.
