A Tesla (TSLA - Get Report) big rig could be a huge event for the trucking industry. 

"We believe Tesla's truck reveal in September will be one of the biggest catalysts the trucking industry has seen in decades. We also expect Tesla will announce carrier/shipper partners," Morgan Stanley analyst Adam Jonas wrote in a note on Monday. 

Jonas added, "If Tesla opens up its order books and picks up a large number of orders in a short time-frame (we note that relatively unheralded Nikola Motor picked up 8,000 orders in just 6 months), it could set off an arms race among both carriers and incumbent OEMs to get electric, autonomous trucks to market."

Tesla Inc. is developing a long-haul, electric semi-truck with autonomous driving capabilities that move in "platoons" and automatically follow the direction of a lead vehicle, Reuters reported recently.

The electric carmaker is said to be nearing the completion of a prototype of the trucks, according to an email obtained by Reuters between Tesla and the Nevada Department of Motor Vehicles.

One person that probably isn't feeling this news is billionaire Warren Buffett.

"Autonomous vehicles would hurt us if they spread to trucks," Buffett told shareholders at Berkshire Hathaway's (BRK.A - Get Report) annual meeting in May. If self-driving trucks become predominant on the roads, it could steal business from Berkshire owned railroad Burlington Northern, Buffett hinted.

Buffett acknowledged that autonomous cars are "coming", and could also "hurt" Berkshire's insurance business Geico. After all, driving hands free is much riskier than driving with two hands on the wheel.
To be sure, Buffett is right that autonomous cars are on the way.
By 2035, more than 12 million fully autonomous vehicles are expected to be sold per year globally, according to research firm BCG.
