Tesla CEO Elon Musk announced in April [arstechnica.com] that the company is working on pushing a long-haul electric semi truck to market, which is set to be formally revealed in September. Now, Reuters has viewed e-mail correspondence [reuters.com] between Tesla and the Nevada Department of Motor Vehicles that indicate that the company has discussed testing semi trucks on the state's roads.
The Reuters report also mentioned that the semis would be outfitted with autonomous functions, so they could traverse the nation's highways without a driver in the front seat. The e-mails seemed to indicate that Tesla's semis would "platoon," that is, drive in a formation such that a number of trucks could follow a lead vehicle. It's unclear whether the lead vehicle would have a driver, or operate autonomously with a person in the front seat to monitor safety.
[...] Reuters also reported that California DMV officials will meet with Tesla this week "to talk about Tesla's efforts with autonomous trucks."
