Really, with the number of crashes that had been like Wheldon's in the past at the 1.5-mile ovals, it was a ticking time bomb. Davey Hamilton survived a bad crash but sustained major injuries; Kenny Brack did as well at the same track, Texas; Ryan Briscoe had a nearly identical crash at Chicagoland. Dario Franchitti flipped TWICE in one season. They've known for a good long while these cars are prone to flipping at high speeds. And they thought they had a solution to try and put an end to this, but it was one race too late.
It's a tragedy that probably didn't even have to happen if the right measures had been taken sooner. Goodbye, Dan. We will all miss you.
