It is fascinating to see the different approach to risk in those times in comparison with nowadays. Spectators, photographers, stewards, pit crew,... everyone was so near the racing cars. In particular , the unprotected pits were so noteworthy. A simple mechanical accident or a minor contact between two cars and there could be a catastrophe. Very speciall the case in LeMans: they ran 24h, including night, dawn, dusk, fatigue, heterogeneous cars, ... passing at high speed meters away the unprotected pits. However, very few incidents happened in hundreds of races with people so close to racing cars. In fact, it is almost unheard any catastrophic event of that kind. From a purely practical point of view , it seems it is not so dangerous, statistically speaking... but I would never be so close to a racing track! IMO, nowadays, we are in the extreme opposite position (in Western countries). The safety distance is so big that I think it is overdone. Always there is a risk in anything you do, the key is to assess it in a rational way. You cannot sacrifice everything because of safety, otherwise you would live a pretty bland life. Lol , my post became too philosophical when I just was enjoying the view of racing in the 70s!
Not cool. Just common sense and normal attitude. Life is dangerous and deadly. You think you'll live forever don't you ? I'm amazed how much people nowadays have become so obsessed by security. Be aware, there are viruses outside. Don't go out!
