Space Precinct (1994)

Episode 59 is here with Gerry Anderson's Space Precinct, it has flying cars alien more aliens and space police

The year is 2040 and there's not a lot of backstory to fill in the gaps, so lets say the human race meets some aliens and some of them want to be Cops and some Gangsters.

The series is set in the year 2040 and starred American actor Ted Shackelford as former NYPD detective Patrick Brogan, now a lieutenant with the Demeter City police force on the planet Altor in the Epsilon Eridani system. Brogan and his partner Jack Haldane (played by Rob Youngblood) must adjust to living in another solar system, and investigating crimes being committed by aliens as well as humans (that's more backstory than the pilot episode told us).
