Tesla’s quest to become a player in the commercial truck segment is off to a good start. It’s barely been a week since the electric automaker’s new semi trucks were unveiled and the company already has a pre-order of 15 units from Walmart. The world’s biggest retailer is no stranger to commercial trucks with around 6,000 units at its disposal. The new Tesla trucks, though, could be a game-changer for a company as big as Walmart that relies heavily on long-haul deliveries of all of its merchandise. Of the 15 pre-ordered trucks, five will be used for the company’s business in the U.S. while the other ten will be used up in Canada.
