Go on the Indycar forum and look at the resistance to replacing the fences with something better. No safety improvements are ever made until it is absolutely forced. There are a few exceptions like SAFER and HANS, but for the most part you have to kill a few people before everyone else wakes up. Incredibly, they were killing drivers 2 or 3 a month back then and still no one would listen. Jackie Stewart was pretty much out there by himself trying to get things done.
We look back now and think it was stupid to race under those conditions, but what are we going to say in 10 years about how stupid catch fencing and open wheels, open cockpits are today?
You can be a critical fan without being a Critic... Or can you? Quit your b'tchn and enjoy the racing :D
