Be honest. Besides maybe the Hollywood sign, this is probably what you think of when you picture LA. And now, the idea of a no car Olympics in just four short years is hard for many to imagine, but that's the plan.

Part of having a no car Olympics means getting people not to drive, but also using public transportation to get to the games.

The 2028 Committee is aiming for the country's most climate-conscious Olympics.

What people are going to see is a really different city than maybe what they are expecting.

Plans are still in the works, but organizers say part of the deal is making LA's already pre-existing Olympic venues only accessible by public transportation. To pull it off, the county is borrowing nearly 3,000 busses to drive an estimated one million more trips a day, including venues spanning as far as 85 miles across the region and asking people to keep the roads clear by working from home. Local transportation officials say that would cost the LA Metro system at least a billion dollars, and it's not clear who would foot the bill. Safe to say, many Angelenos are a little bit skeptical.

I don't think it's possible. I would opt to leave town before I would take public transportation.

Transportation Professor Jim Mohr says it's a bridge too far for a city that doesn't rely on public transportation, and safety is a big sticking point.

The reason the transit system doesn't feel safe right now is because it's not. And there's a lot that we need to do to make it safe.

But this isn't the city's first rodeo.

No traffic. It's just wonderful. Everybody should take the bus.

Metro is hoping they can repeat the success of the 84 games when despite high volume, drivers reported little congestion thanks to flexible work hours.

La hosted the Ares Tour. That event really gave us a lot of encouragement. People really would be willing to get around differently.
