Tesla seeking to test driver-free electric trucks on public roads

Leaked correspondence with Nevada vehicle regulator reveal Elon Musk's plans for fully autonomous electric freight

Tesla is working on electric, self-driving trucks that can travel in "platoons" or road trains capable of following a lead vehicle, according to leaked correspondence with regulators.

The electric truck, which is due to be unveiled in September by Elon Musk's electric vehicle company, is close to prototype on-road testing, with both Nevada Department of Motor Vehicles (DMV) and California officials in talks to permit trials on public roads, according to documents seen by Reuters.
