I agree with Belatti and Timbo. Actually, when I posted before, I wrote something really long and boring about how you don't change accident rates unless you change the road and how I do not see the radical differences between F1 cars safety measures and regular ones, but I thought that would be OOT...
What have really changed in the cars? What touts FIA about in its page about safety? Collapsible steer column, harder chassis and HANS. That's it.
The cars still fly when they make wheel contact, for heaven's sake. Tracks like Catalunya still have improvised barriers. Even NASCAR has aerodynamic devices designed to avoid that, FIA has not found what to do yet. Discussing the new Concorde agreement they are worried about the teams getting more money.... from racing fees they charge to track owners. Way to go.
