People in Los Angeles are known for their love of cars. The city is very large, and its public transportation is slow. So people drive everywhere. But now, a group of bicyclists are trying to get people out of their cars and on bikes.

Devon Fitzgerald says he has to be careful when he rides his bike in the streets. “A lot of people are in a rush, and it's very difficult to keep careful, for they would rather care for their speed than your safety.” Although riding a bike to work can be dangerous, he prefers it to a car. “It's much simpler than driving a car. For example, I don't have to worry about parking.”

Roger Rosas drives to work. "You always have to make sure you look to the other side because someone would rush across by bike. Or you can easily get into an accident. "

To make bicycling safer, some people who live and work near each other are riding to work together, which they call a "bike train". Nona Varnado helped create the group L. A. Bike Trains. "You're in a big group. If you're afraid of riding alone, you can now ride with experienced riders. " Nona said that people would feel safer by riding together in a group.
