It would have to be a very special dart. Cars are mostly aluminum and foam. A piercing dart would be dangerous and a magnet would really work.
I never thought of my Olds Silhouette minivan as a high performance car. Neat.
The rubbery panels were great. I was at school pickup and another parent backed into it. They crushed the front fender to the firewall. Then they pulled up and it popped out.
They were freaked out but it was fine. And it's just a car.
