U-ber Turn
A sudden unsignaled U-turn or three-point turn by a rideshare driver across a double-yellow center line (or where otherwise prohibited,) usually during rush-hour traffic, performed without regard for common sense, nor safety, nor inconvenience of oncoming or following traffic.
My Uber driver made an illegal U-ber turn in the middle of Main Street at 5 P.M., so I only gave him 4 stars.
