If you live in LA, look out for the new bus on the orange line. It's the longest bus in California. The MetroLiner is 65 feet long, five feet longer than normal buses are allowed to be by law. It had to get a pass as a prototype to drive on California roads. The extra 5 feet allows another 20 passengers to fit in the bus bringing the capacity to 100 people. The bus runs on clean natural gas.
