Final answer:
The broken mirror is not a direct cause of the car accident; relevant factors could include weather conditions, other drivers' mistakes, or mechanical failure. Driver error is a significant factor in accidents, and the influence of the moon's brightness would need substantial evidence to be considered.
Step-by-step explanation:
The cause of the car accident in this scenario needs to be determined based on evidence, not superstition such as the belief in bad luck from breaking a mirror. The broken mirror itself is not a direct cause. Possible direct causes could include weather conditions, another driver's mistake, or a mechanical failure. The driver being blinded by the moon in a separate instance seems unlikely, as the moon is not typically bright enough to cause blinding. However, if sufficient evidence suggests that the lunar brightness at that specific moment was intense due to atmospheric conditions or other factors, this claim might warrant further investigation. Generally, driver error is a considerable factor in accidents, as suggested by the American Automobile Association, citing that driver error accounts for a significant percentage of fatal accidents.
