The implementation of a mandatory demonstration of Tesla's driver-assistance technology, including Full Self-Driving, before finalizing sales introduces a new step in the sales process. This requirement, as stated by CEO Elon Musk, is expected to slow down the delivery process. Given that delivery speed is a key factor in sales volume and customer satisfaction, this policy could lead to a short-term decrease in sales volume. A decrease in sales volume, in turn, could negatively impact Tesla's stock price in the short term as investors react to potential delays in revenue generation.
