It doesn't give his wife someone to talk to or his kids a father to hug. When a fighter dies, we want to ban boxing. If four died in a year, we'd have a federal investigation. In racing we say, well, uh, geez, at least The Intimidator died with his boots on.
Tragedy lingers until something is done to make it go away.
Wouldn't want to be hasty. You make drivers wear closed helmets, not open-faced jobs such as the one Earnhardt wore. You take this HANS device and bolt it into every seat in every stock car. If the tech geniuses can figure ways to streamline vehicles and hype motors to achieve inhuman speeds, they can find a way to soften walls so drivers don't die. If they want to.
