Imagine: You're out on a nice drive when you turn a corner and someone, busy doing a livestream instead of driving, merges without looking, smashing into your car. Vexing, but no worries; you get out to assess the damage and exchange insurance information.
The only problem is the other driver has a different story of the events. They claim you cut them off. Several witnesses come forward, some siding with you, others siding with the other driver. While cops and insurance adjusters will investigate the scene to determine the cause, sometimes you could do nothing wrong and still be found at fault.
