When I was in my early 20's, my friend's parents bought him a very expensive luxury car with sports package. It wasn't as crazy as Hellcat, but still a rocket. Few months later I attended his funeral. The look on his mom's face was heartbreaking.
He drove too fast and didn't stop in time. Collided with a truck. It's very tempting to go fast when you're driving a powerful vehicle.
If a parent can't change a kid's mind about buying a muscle/sports car, the very least that can be done is driving/racing lessons.
Proper training is a must!
