If a Large Solar Flare has a 12% chance of hitting earth in the next 10 years what is the chance in 100 years?

If you understand probabilities whether an Electronics killing Solar Flare hits earth in the next 100 to 300 years "IS NOT IF BUT WHEN" then you get where I'm going with all this.

My biggest fear with all of this "and I've written about this before" is that it will come when almost no one drives a car and all cars are self driving pretty much and all planes are self driving and we are REALLY dependent in an unhealthy way on computer "Sentience" to an extreme degree as humanity.

That would be really bad because imagine all passenger planes in the sky over earth (6000 at a time) simply all falling out of the sky at once (then multiply approximately 100 per 6000 planes which is about 600,000 people falling out of the sky in those planes). Then imagine how many people would be in self driving cars. What would the cars do all over the world that were self driving? How many people would die from that?

So, all this should be taken into consideration as people build self driving cars and self driving planes, because according to my calculations millions of people would die when that solar flare hit. So, if failsafe programming isn't put into planes and self driving cars by then, then all insurance companies at that point are going out of business who insure those air and land and sea vehicles very soon after that event. And companies who haven't prepared for this outcome would soon be out of business as well.

But, that might not be the worst thing, because countries that weren't hit because they were on the other side of the world when it hit might attack the vulnerable countries that were hit.

And the countries hit by the solar flare might just collapse under the grief of millions of people dying at once. So, insurance companies, and nations need to prepare for this outcome because:

"IT IS NOT IF IT IS ONLY WHEN".
