Another major difference (I would have thought) is that this type of Indycar track, being oval, means that there are more cars on a shorter lap (meaning more chance of them bunching) and going at a much faster average speed – basically any accident at any point could be potentially very serious, whereas on an F1 circuit the accidents would be more likely to happen at the start (ie first corner) or during the race on a corner when speeds are naturally much lower.
Agreed.
One of the reasons I don’t watch IndyCar is that it’s inherently too dangerous. In F1, if a car crashes out it usually leaves the circuit, scrubbing off speed until hitting tyre barriers. Cars rarely flip over (I’ve seen it only a couple of times in the last 20 years) and even if there’s a direct hit into a solid object, the crash structures are so strong that there’s rarely a problem. There’s often some debris remaining on the track, but it’s less likely to be big stuff; you do tend to get punctures, but then again again, these rarely cause huge accidents
In oval racing (all types, not just IndyCar), if someone crashes high into the wall, the debris remains on the track, bounced back into the path of the oncoming cars. There’s solid stuff to hit, not just tyres to damage. Added to that, there’s a significant difference between open-wheeled cars versus NASCAR, trucks etc in that that there’s just far less protection if the vehicle rolls, which, with the speed of IndyCars (225mph) and the constant lateral loads, is far more likely in IndyCar than F1. Add to this the fact that it was a small oval and that there were a very large number of cars, and the crash and resulting fatality is not a surprise.
Ask an open-wheel racer what they fear the most (other than losing a sponsor) and they’ll tell you that flipping the car is right up there.
