I watch all sorts of racing and enjoy them for their differences but there are a lot of people out there, especially in the states that say formula one racing is boring because there isn't a lot passing on the track and that qualifying determines the race winner more then anything else(which Vettel has backed up this year in f1)
There's been more passing in recent years than there has been in the past and while Vettel has dominated nearly always from pole, the last race being the exception, this was truly a perfect season(so far) for Red Bull Racing. You really shouldn't look at this year as the norm though, last year at this time, there were 4 guys with a chance to win it all, but RBR just blew everyone away this year. I mean, Vettel won most of these races without any real challenge, so they truly just have had the best car, always getting pole was just a byproduct of such.
As for what you said about Wheldon testing the next gen chassis, I actually read an article about him and the chassis in Road&Track or Car&Driver, one of the two, I mix them up, but point is, it was weird reading it now knowing what happened. With any type of open cockpit car you're gonna have problems like this. With the head exposed, it's always a safety issue. In F1 a couple years ago, Filipe Massa was struck in the head by a spring that fell off another car's suspension IIRC, which could have been worse than it was. I hope that IndyCar can learn from other open wheeled racing formulas, such as F1, seeing as they have a really good safety record, having gone without a driver death for 17 years. Indy cars are a bit smaller than F1 cars, but maybe they can make the chassis/safety cell of the car a bit wider and seat the driver a tad lower, as to try to avoid this type of injury in the future.
