In a lot of cases adding your child as a primary driver to a very expensive car will significantly increase the cost of the insurance. My brother quadrupled my father's insurance price, for instance, because he was a teenager. Most people can't afford to just eat the increased monthly, so they have to balance the need to have their kid be functional in the real world with the need to make sure their kid is "safe." A lot of older vehicles are still fairly safe in common accidents, as "older" in many cases means driver and passenger airbags, seat belts, crumple zones, and so on. I think the most you can say here is that you can afford to have your kid drive the Tesla. Many people can't. I could make some points about how the NHTSA values occupant safety over the safety of people in other cars but that's a totally different discussion.
