TOKYO (AFP) - Japans Toyota Motor on Monday said it planned to create a private social networking service that will let cars tweet their drivers when they need servicing. The Japanese automaker said it would work in conjunction with US cloud computing firm Salesforce.com to create the Toyota Friend service for owners of electric cars and plug-in hybrid vehicles to be introduced next year. In a demonstration at a Tokyo showroom, an owner of a plug-in Prius hybrid found out through a cell phone message from his Prius called Pre-boy that he should remember to recharge his car overnight. When the owner plugged in his car to recharge it, the car replied, The charge will be completed by 2:15 a.m. Is that OK? See you tomorrow. The exchanges can be kept private, or be shared with other Toyota Friend users, as well as made public on Facebook, Twitter and other services, the company said. The companies did not give details of how the technology, such as the content of the talking cars dialogues, will be managed. But officials said the answers will be automated through sensors in the car.
