Pluto Corporation is sued in two wrongful death cases. In the first case, Wendy claims that her deceased husband died in a car accident because Pluto did not fix a dangerous flaw in its seatbelt design. Pluto argues that there is no proof that Wendy’s husband was wearing a seatbelt at the time of the accident. Wendy calls her husband’s coworker to testify that in several decades of riding to work together, her husband always wore his seatbelt. In the second case, Harry claims that his deceased wife died in a car accident because Pluto did not fix a dangerous flaw in its brake design. Pluto argues that it did not know about the flaw and calls an employee to testify that there have been no other accidents resulting from a brake failure in Pluto’s cars.

Should the coworker’s testimony and the employee’s testimony be excluded?
