Uber, Lyft, Sidecar and other ride-sharing services just suffered a huge setback in Seattle, and it's way more serious than getting their vehicles' tires slashed by irate competitors. The city's council members have decided to uphold a decision they made in February -- one that caps every platform's active vehicles to a measly 150 each. According to TechCrunch, the decision was a result of various complaints and questions regarding these services, which you can use to summon cars through mobile apps, as they're relatively new. Most of those were concerns for public safety, even though the companies already screen their drivers (in California, at least) and are expanding their insurance coverage. Considering Uber claims to have roughly 1,000 drivers in the city, this move will not only put many of them out of work, but also severely limit each company's capacity to meet demand.
