Tesla is set to deliver its first shipment of semi trucks to Pepsi tomorrow. This will be a new, improved model for commercial goods shippers that have previously been dependent on the price of oil to ships goods. When oil prices are high, consumers have paid more for goods in the past because gas-based semi trucks have had to pay more for gas, thereby, adding to the supply-chain costs of shipping commercial goods through the supply-chain to end-consumers. With the introduction of EV-based Tesla Semi trucks, the supply-chain costs of shipping commercial goods will be reduced leading to a cheaper total cost of goods for end-consumers.
