Former President Donald Trump on Friday proposed building up to 10 futuristic “freedom cities” on federal land, part of a plan that the 2024 presidential contender said would “create a new American future” in a country that has “lost its boldness.”

Commuters, meanwhile, could get around in flying cars, Trump said – an echo of “The Jetsons,” the classic cartoon about a family in a high-tech future society. Work to develop vertical takeoff and landing vehicles is already underway by major airlines, auto manufacturers and other companies, though widely seen as years away from reaching the market.

“I want to ensure that America, not China, leads this revolution in air mobility,” Trump, who announced his third bid for the presidency in November, said in a four-minute video detailing his plan.

He said he would launch a contest to charter up to 10 “freedom cities” roughly the size of Washington, DC, on undeveloped federal land.

“We’ll actually build new cities in our country again,” Trump said in the video. “These freedom cities will reopen the frontier, reignite American imagination, and give hundreds of thousands of young people and other people, all hardworking families, a new shot at home ownership and in fact, the American dream.”
