You don't seem to understand what free will is. Free will is a choice by a sentient mind. A random brake failure has a cause and effect, but is still not due to free will.
lol, I understand free will.
brake failure alone don't necessarily lead to death. drivers can make different choices in the event of brake failure that can have very different results.
Recently a remote volcano errupted, not an accident, and not a natural calamity as a stand alone event, IT was the choice people made to risk visiting the volcano that resulted in their calamity.
