    Given a list of available delivery drivers and their predicted delay times based on current traffic and weather conditions, determine which driver will experience the least delay on their route. Each driver-delay pair is represented as a tuple containing the driver's ID and their estimated delay in minutes, and you need to return the ID of the driver with the minimum predicted delay.
