(Established) scientists have a long history of ignoring new theories not science itself. But that’s because at the end of the day scientists are still human.
Science is not great at working on a very short time scales. But give it enough time so more evidence is gathered and possibly some stubborn influential people (that can’t accept a new theory) die and generally we get closer and closer to truth.
Cars are also not safe, especially at 200+ km/h but somehow it’s OK to drive them this fast in Germany.
Edit: What I want to say is that there is no absolute safety.
