Ever wonder what it's like to be a part of the country's on-demand transportation revolution, a fast-growing industry that is redefining the way people travel in big cities? Guy Adami of CNBC's "Fast Money" took a few hours off from trading to test out life as a hired driver in the sharing economy.

Lyft, which launched in 2012 and competes with Uber and other on-demand ride companies, has more than 100,000 drivers, and shuttles passengers on an estimated 2 million rides per month, according to the company. It currently operates in more than 60 U.S. cities and says it's launching in new cities "every week."

To date, Lyft has raised more than $1 billion in funding from big players like Carl Icahn and venture capital firm Andreessen Horowitz.

Adami, who heads advisor advocacy at Private Advisor Group and is an original member of CNBC's "Fast Money" team, traded in his office chair for a chauffeur hat and white gloves to find out exactly what it's like to drive passengers around on the app-based platform.

"That's not easy work, that Lyft driving stuff," Adami said of his experience.

Renowned tech investor Roger McNamee, who co-founded venture capital firm Elevation Partners, which has investments in companies like Facebook and Yelp, said the emerging smartphone-based economy is among the "biggest things going on" in the world right now, and companies like Lyft are playing a big part in it.

"We've spent the last eight years selling the world smartphones, and it was all about the adoption of smartphones. We've now sold a billion of them," he told CNBC. "So the key phase that we're in now is adaptation to the real economy. And the first piece we saw was transportation around Uber and Lyft."

McNamee, whose firm does not currently have a stake in Uber or Lyft, added that Uber is the "best single idea" to come about since Facebook, and it's a "giant game changer."

Adami, on the other hand, won't be getting back behind the wheel of a Lyft car anytime soon. While he said he "had a lot of fun as a Lyft driver," and "met some great people," Adami said he was going to stick to what he knows best: trading.
