According to a Bloomberg report, which cited an unnamed person familiar with the carmaker's plans, Tesla may be taking its first steps in that direction by unveiling a suite of new high-tech features including one that can keep the car in its lane.

Musk's tweet on Oct. 1 said that the company would unveil "the D and something else" on Oct. 9.

Automated lane technology is expected to be the next area of technology automakers will be including in cars. Some features would be used on highways with clear lane markings, where on-board sensors could work to help keep a car in its lane.
