Uber Sued After Alleged Wild Ride with Sleepy Driver

Uber's been sued again -- this time because a driver was allegedly delirious behind the wheel, and then went on a campaign against the passenger to keep her yap shut ... according to a new lawsuit.

Marisa Hyland says it all went down last summer in NYC, when a driver named June repeatedly averted crashing by a whisker during a 4 mile trip to work. Marisa says June told her she was "delirious" from an all-night shift and needed some ZZZ's.

Marisa says she demanded out and once on safe ground, called Uber again and belatedly got to her destination.
