If people don’t like the rules or want something safer then they can do something else more challenging,
In the early days, people opposed seatbelts on the grounds that it was safer to be thrown clear of the vehicle than to be trapped and burned alive. One of my dad’s mates was a truck driver who served in WW2 and he refused to wear seatbelts on those grounds. In the 1960s, motorsport deaths were commonplace, but then people such as Jackie Stewart started demanding safety standards. The death of Jim Clark and the near burning alive of Nikki Lauda were big motivations to improve safety. JS and NL weren’t cowards, they just didn’t see why things should be unnecessarily dangerous. More recently, the deaths of Henri Toivonen and Aryton Senna served as wake-up calls to improve things.
Some risks are part of the sport. For example, racing in the wet is risky, but it is part of being a race driver and it makes for very exciting races, so it’s a risk the sport needs to keep. Drivers being hit by debris does nothing for the sport, it’s just an unnecessary danger. Massa was extremely lucky to have not been killed by debris and there was nothing he could have done to avoid that, it wasn’t a matter of skill, just of bad luck. Yes, the Halo or a windshield don’t look like what we are used to. So what? I’d rather look at ugly cars than have drivers killed for no reason.
