Point of Divergence
In OTL, Archduke Franz Ferdinand of Austria and his wife Sophie, Duchess of Hohenberg, were in a motorcade in Sarajevo where Gravilo Princip was waiting. The driver of the Archduke's vehicle took a wrong turn as it drove past, near the Latin Bridge. After realizing the mistake, the driver put his foot on the brake and backed up. During this, the engine stalled and gears locked, leaving the Archduke open for assassination.
What if? What if the car hadn't stalled and the driver was able to leave the area, and not giving Princip the opportunity he needed to assassinate the Archduke.
