“Going forward, it is mandatory in North America to install and activate FSD V12.3.1 and take customers on a short test ride before handing over the car,” Musk wrote in an email to staffers on Monday. “Almost no one actually realizes how well (supervised) FSD actually works. I know this will slow down the delivery process, but it is nonetheless a hard requirement.”

I mean, you can require the employee delivering the car to offer to take the customer on a ride. You can require the employee to tell the customer how awesome the service is. But I don't see how you can make the customer go for a ride if the customer doesn't want to go for a ride. And, frankly, I kind of suspect that a not-inconsiderable number of new customers just want to go use their new car and aren't interested in sitting through a sales pitch for some associated service.
