Back in the olden days of car racing, safety came last. Not only there were not roll bars or seat belts, but they consciously constructed racing cars from highly flammable light materials just to shave off a few pounds of weight, even if it meant almost certain but also very painful death in a case of a violent crash.
Racing infrastructure was concurrently poor, lacking catch fences which for example could have prevented the death of 70 spectators at 1955 Le Mans. Yes, you read that number right. Chilling.
