Transit planners at UC Davis and AAA will be giving away 100 hundred plug-in Toyota Prius hybrids to families chosen from the AAA database. Like other plug-in vehicles we've seen, these can get 100 MPG and are blind crushingly quiet. Testers will only get to try out the cars for eight weeks and will be constantly asked how they're liking them, to which they'll predictably reply: "It's so quiet" and "I don't have to put as much fuel in the car." The ultimate goal is to get people to think they could drive plug-ins by giving them plug-ins. Brilliant![SF GATE]
