A 68-year-old city man was killed Monday by a hit-and-run driver who may have been tooling around in a Lamborghini, cops and law-enforcement sources said.

Victim Ismael Rodriguez of The Bronx was crossing the intersection of Park Avenue and East Tremont Avenue in the Tremont neighborhood — about three blocks from his home – when the motorist slammed into him just before 6 a.m. and kept driving, police said.

The impact knocked the senior off his feet, and he was pronounced dead at the scene, authorities said. 

The driver, who sources said was in a white car, possibly a Lamborghini, has yet to be caught.

The deadly hit-and-run came on the heels of another fatal crash on the Lower East Side of Manhattan – where 15-year-old Citi Bike rider Daria Serkov was struck and killed by an excavation truck while with her 13-year-old friend Friday night.

The unidentified truck driver remained at the scene at East 14th Street and 1st Avenue and wept when he realized what happened, eyewitnesses told The Post.

The younger girl was hospitalized but survived the horror. 

Earlier this month, an elderly man was also fatally thrown off his e-scooter in a head-on, broad-daylight collision with a bicyclist outside a Hilton hotel in Downtown Brooklyn, police said.

Thomas Bakas, 77, was riding his stand-up electric scooter in the bike lane on Schermerhorn Street near Smith Street on Sept. 7 when he smashed into the bike rider heading in the opposite direction, authorities said. 

Bakas, who lived just blocks from the scene, was taken to Brooklyn Methodist Hospital, where he was pronounced dead, police said. 

The bicyclist stayed at the scene and was neither hurt nor arrested, cops said.
