No, it is not mandatory for every individual listed on your USAA auto insurance policy to participate in the SafePilot program. However, the extent of the discount you might receive can be influenced by the number of eligible drivers on your policy who choose to use the app. While each participating driver has the potential to contribute to the overall discount through safe driving habits, non-participation does not disqualify the policy from receiving a discount altogether. Participation is optional, and each driver can decide whether they want to join the program. The more drivers participating, the greater the potential savings could be, based on the collective driving data and safety scores accumulated through the app. Each individual who signs up for the program in your household will be tracked separately from the other enrolled drivers when operating the vehicle.
