Certainly one should not be racing cars where they can hurt people, and a track would be best. However, being a crazy Tesla owner, I have been known to demonstrate my car's acceleration on a stretch of straight unoccupied country road. I have driven fast, at times, many times in my life and I'm aware of how a little abrupt movement of the steering at speed can cause devastating loss of control. BUT I still do it, because I AM in control and never make any rapid steering movements at speed. It can be done safely.
I suspect accidents happen to people who get out of their experience zone. I allow people to drive my car, but I am in front with them and insist that they accelerate and steer gently, at least until they get some idea of the amazing acceleration and power, and I own the Long Range, not a Performance. I've never come close to an accident while showing off my car.
