Not certain if it has flying cars (still researching), but that sounds a bit like the plot of Gamer from 2009.
In 2034, [computer programmer] Ken Castle (Michael C. Hall) invents self-replicating nanites that replace brain tissue and allow humans to control other humans' actions and see through their eyes. The first application of Castle's "Nanex" technology is a virtual community life simulation game, Society, which allows gamers to manipulate live actors as their avatars. Society becomes a worldwide sensation, making Castle the richest man in the world. He then creates Slayers, a first-person shooter where the "characters" are death-row prisoners using real weapons in specially created arenas. Unlike Society actors, Slayers participants are not paid; instead, they volunteer in exchange for the promise that any Slayer who survives 30 matches will earn his freedom (though no one ever has).
John "Kable" Tillman (Butler) is the crowd's favorite, having survived a record 27 matches (no inmate before him has managed to last more than ten). He is exclusively controlled by Simon (Lerman), a seventeen-year-old superstar gamer from a wealthy family.
Ah, and with a bit of further exploration, there are no clones or life-extension, just nanite-based mind control. Still, this fits as a decent partial answer in the right timeframe.
