user: What are the three best rapid transit systems in California and why?

assistant: 1. The Bay Area Rapid Transit or "BART" because it has many different lines and connects most of the San Francisco Bay Area.
2. MUNI because it has a wonderful combination of some light rail lines, vintage vehicles and lots of bus lines.
3. LA Metro because it connects so many different places in the huge LA metropolitan area where automobile congestion can be bad.
