Uber isn't the only ridesharing outfit running into legal trouble these days -- Lyft is now facing a lawsuit over claims that it deprived new drivers of promised bonuses. The transportation company allegedly committed fraud by offering $1,000 to drivers who completed their first ride by March 5th, only to renege for many of them because it couldn't finish background checks on time. Lyft isn't offering a formal response to the suit just yet, but the company tells the AP that thousands of would-be drivers made it under the wire. However, lawyers maintain that hundreds of others didn't -- there could be at least $5 million up for grabs, according to the attorneys. It's too soon to declare a victor, but it won't be shocking if the pink mustache company is more cautious about handing out cash in the future.
