Light Rail in Grand Theft Auto 5
The Los Santos Transit (or "Los Santos Transit Authority", "LST") is the division in charge of mass transit and public transportation in the city of Los Santos
Why not leave your car in your Garage, and take public transportation to your destination? The Los Santos Transit System covers almost all of the city of Los Santos, so you should be able to get to your destination easily, and help lower the pollution in Los Santos.
