I know they aren’t “designed” to go around banked corners, but they are capable of doing it. Indycar has 1 chassis for Ovals and Roadcourses, and thats because it is possible for one to race on the other and vice versa. Not to mention the fact that F1 cars are better suited for it, since they generate more downforce. It would be safer to take an F1 car around Indy than it would be to take an Indycar around there, just because of the amount of downforce F1 cars generate, and the amount of mechanical grip they have. Indycars are designed for racing on ovals, but that doesn’t mean the chassis is made specifically for them. It means the aero package and design allows for close racing at speeds of 210+ MPH. F1 cars wouldn’t be doing that, they would just have to take the corner flat out once every lap. Indycars do it “4″ times every lap, and; 1, crashes don’t always happen, and 2, when they do, the drivers are safe (That is unless they go into the catchfence).
Taking off from a crash shouldn’t be a problem here, just because of how little space there is between the apex and the wall. There isn’t enough road for the cars to take off, unless they go over eachother. In that case, any turn is dangerous, because a car can climb over another car at any turn (and in any open wheel car). So this is a fast corner, but I don’t think this is something to be freaking out about, particularly not with todays safety.
