PlanetTran is an all hybrid car service based in Boston. With a fleet of 12 Toyota Prius and two Lexus hybrids, they can drive you anywhere you want to go.
They are not a taxi service, however, so no curbside or hailing them on the street. Instead, you will need to make a reservation. PlanetTran expects most of their business will come in transports to Logan airport.
Larger bags (golf bags and such) may cut down the number of passengers to 2 in a Prius. But they can normally seat four plus the driver.
