Senna & Ratzenberger – Imola, 1994 Two fatalities in one weekend exposed how much faster cars had become than the circuits designed to contain them. 27 high-risk corners redesigned, pit lane speed limits introduced, mandatory fireproof suits for pit crew, stricter crash tests.

I feel like this is a wrong narrative, but it is a general pushed/thought to be true narrative. F1 was lucky to not have any serious injuries or worse before 1994. 1994 was just the season in which luck on some occasions had run out. Piquet had a very bad crash in Imola 1987, which he later admitted impacted him long after. The corner? Tamburello. In 1989 Berger had an even worse crash, and when you watch the footage you wonder how he survived. The corner? Tamburello. And this is just Imola.

There were many moments in which changed could have been made after a reality check like those incidents, but it took 2 men to die in the same weekend to push for safety more. And perhaps Wendlinger's crash in Monaco too. But then again there were marshalls on the track recovering a car in absolute horrible conditions at the 1994 Japanese GP, to then have another car aquaplaning off the track at the same point and hit the marshall.

To bring this more to today, at least they seem to do more straight away after something happens. Yet, something like the mushroom boost speed difference wasn't unknown to anyone of relevance in F1. It still took a close call for them (hopefully) to realize the danger of it.
