More dangerous than WRC, with production car based chassis on loose surfaces with trees right alongside?
More dangerous than IndyCar, with higher top speeds and the challenges of pack racing on ovals?
More dangerous than Top Fuel/Funny Car/Top Alcohol racing, with the incredibly high acceleration and trap speeds, and the terribly narrow margins of error?

They've spent a lot of time and even more money making these cars as safe as possible, to the point where we have the drivers so buried in the cockpit that they cant see their own wing mirrors. They have the wheelbase of your average freight lorry, so they're incredibly stable in the handling department. And they can't push flat-out, because the rules stop them from doing so with the lack of tyres and the engine mileage limitations and the fuel and...
