Giving a major fillip to key buzzwords in the transportation industry, Tesla Motors Inc is now planning to diversify into fully-autonomous driving, car sharing, electric semi-trucks and cargo transportation. To achieve the fully-autonomous driving, the company is planning towards a total of six billion miles of test-driving. Its new line Tesla Semi is specifically being designed for cargo and transportation services wherein the role of a driver is to get upgraded to be a fleet manager. No longer merely a car company, Tesla is now expanding to cover major forms of terrestrial transport.
